Emerl as he appears on Sonic Channel.

Emerl (Emeru) is a fictional character in the Sonic the Hedgehog series, first appearing in Sonic Battle.

Emerl is an ancient weapon known as the Gizoid discovered by Professor Gerald Robotnik. Gerald attempted to nullify his destructive programming, but failed. In an attempt to curb it, he gave it the same qualities as his creation, Shadow the Hedgehog, a "soul" based on that of Gerald's granddaughter, Maria Robotnik.


Doctor Eggman takes the Gizoid in the hopes of using it to rule the world, but tosses it aside when he finds no use for it. Sonic the Hedgehog finds it on a beach, names it Emerl, and he and his friends teach it how to fight. As the player plays the Story Mode, Emerl learns the abilities of the various other characters.

Emerl's principal power is perfect copy: He can observe a technique, skill, or trait in action and then remember and copy that technique with unnerving accuracy and precision. This apparently extends to all aspects of a target outside of its physical form, enabling to mimic running speed, jumping ability, stance, voices, attacks, and even coloration. Interestingly, Emerl also has a set of skills he acquired 4000 years ago before he was shut down; powerful and destructive, they can be unlocked by the player in a special Colosseum gauntlet that is only available in Emerl's Story Mode.

Emerl can also mix and match techniques to suit his taste: Each character has a three hit combo followed by a finisher that sends the enemy flying. Emerl can absorb each of the four different attacks from any character and create an original combo from the data he has (Like so: Rouge ATK 1 -> Shadow ATK 2 -> Sonic ATK 3 -> Sonic Finisher). The combinations are extremely widespread, and because each move has its own power and speed, range from fast to slow, weak to strong, and so on and so forth. If Emerl himself is not physically capable of performing a technique (Tails' Flight ability, for example), he mimics it in another way (in this case, by spinning his arms around his body like a helicopter). This is especially apparent in the case of Chaos' attacks: he is liquid and malleable, which Emerl is not. So, the latter copies by extending his arms outward with a cable-like cord to lengthen his reach. He has shown himself to be capable of Chaos Control (Copying Shadow's Skills) and can summon a Chao to attack enemies (Cream's Skills). Emerl can also summon and manifest weapons for certain attacks (Amy's Hammer techniques and Gamma's attacks).

In Sonic Battle, Emerl is a unique character: During the Story Modes, after any battle Emerl participated in the player receives a card for each character that also participated in the fight (Gamma Clones, Phi, and Emerl himself not included). For example: Sonic, Rouge, Knuckles, and Emerl all participate. Emerl will gain a skill card for each of the former three. What's more, he will also gain skill points after a battle based on how well he fought. If the player wins the battle, he gets one point. If the player wins without getting knocked out once, he gets two points, and finally, if the player wins without taking any damage whatsoever he will gain five skill points. These points have a cap of 500, and each skill can range from 5-30 skill points to use, the most expensive generally being the most powerful, such as the Ultimate Series. During each Story Mode, there are opportunities to "train" with Emerl and the character accompanying him. During these battles, players will take control of Emerl himself and face off against the character he is following.


Emerl was originally created as the strongest and most powerful "Gizoid", a series of robots that can copy peoples abilities, more than four thousand years prior to the game by an ancient civilization of echidnas known as the Nocturnus Tribe (they differed from the Knuckles Tribe as they didn't have spiked fists) referred to as The Fourth Great Civilization by Gerald Robotnik. However, The Gizoid was said to have destroyed the civilization, and was lost. About fifty years prior to the game, Professor Gerald Robotnik found it in a warehouse, and took it to the Space Colony ARK for research. He managed to create a Link with the Gizoid, and figured out that it could learn how to do anything, and that it got stronger when absorbing Chaos Emeralds. He then started Project: Gizoid and equipped the robot with a "heart", a free-willed emotions-based AI. Unfortunately, the project was never finished as Gerald had to hand over the Gizoid to the government in order to buy more time for his Project: Shadow, the research experiment to create the ultimate lifeform. However, the Gizoid soon absorbed a large amount of weapons, and decimated a large section of the ARK. The government then finally decided that Gerald's research was too dangerous to continue, canceled Project: Shadow, and killed or imprisoned all that knew about it.

Sometime prior to the game Sonic Heroes (most likely during his stay on the ARK in Sonic Adventure 2), Gerald's grandson, Dr. Eggman found the Gizoid, and brought it to one of his bases. While experimenting with the robot, Eggman gave the Gizoid a Chaos Emerald which it absorbed. As he couldn't retrieve the jewel, Eggman got angry at the robot and threw it away on a beach, and went to create his own robots, the E-121 "Phi", from the Gizoid's blueprints, making them be powered by shards of Chaos Emeralds. Later, Sonic the Hedgehog found the robot lying around on the beach and tried to communicate with it. The Gizoid only mumbled "Show... power... OR I sh...all ob...ey... Sha...ll conqu...r a...ll..." Sonic answered by showing off a few lightning quick moves. The Gizoid reacted to the moves, and created a Link with Sonic, without him knowing. Sonic, wondering what was up with the robot, decided to take it to Miles "Tails" Prower to ask him about it. However, he stumbled upon Shadow the Hedgehog who demanded that he was given the robot. Sonic fought him off and went to see Tails. He examined the robot and figured out that it could copy abilities and absorb Chaos Emeralds. Sonic and Tails then fought the Gizoid for a while, teaching him their moves. They then decided to give him a Chaos Emerald, and went to visit Knuckles the Echidna in order to borrow the one he currently owned. On the way they met and fought both an E-121 Phi robot and a rebuilt E-102 Gamma , who both escaped. When they finally arrived, Knuckles attacked the Gizoid due to a misunderstanding, but the Gizoid defeated him and absorbed the Emerald. After his second Emerald, the Gizoid learned how to speak, but could only say words that he had already heard, and always repeated them twice.

After discovering how the Gizoid worked, Sonic (in a spectacular show of a lack of imagination) named it "Emerl" due to the fact that it absorbs Chaos Emeralds, and started fighting the robot constantly to teach him new attacks. Tails, who wanted to learn more about the mysterious robot, instead wanted to take him to Central City in order to use a large database to figure out what he was. However, the data was forbidden and Tails and Emerl were attacked by guard robots, from whom they escaped. On the way home, they ran into Shadow, who again wanted to destroy Emerl. Tails and Emerl defeated him, and Rouge the Bat arrived to take the weakened Shadow away. He continued home, only to run into an angered Knuckles who again challenged Emerl, who won. E-102 then found them again, and they had to fight him off. After the fight, Tails finally got home to tell Sonic about the information he had found, namely that Emerl was a weapon. Sonic shrugged it off, and started teaching Emerl more moves.

Three days prior to the game, Rouge had been ordered by the President to find out all she could about the Gizoid. She went to the database, and discovered that Dr. Eggman was already accessing the information. Upon being confronted, Eggman told Rouge that he had already thrown away the robot and then sent a Phi robot to attack her. Rouge destroyed it, kept the Emerald shard and left to find the Gizoid. She found it in the hands of Sonic, and tricked him into letting Emerl listen to her. When Sonic was away, Rouge then swiped Emerl from Amy Rose, who spent time with the robot as she thought of him as a baby project between Sonic and herself. After fighting off the protective female hedgehog, Rouge took Emerl home, fighting Gamma on the way. Once home, Rouge told Emerl that he was to become the world's greatest thief robot. She trained Emerl for a while and then took him along to steal a Chaos Emerald. However, once she got her hands on the jewel, Emerl took it from her and absorbed it, much to her dismay. Sonic then arrived to take Emerl back and Rouge left, saying that the immature robot could never become a master thief. After this third Emerald, Emerl started to talk normally, but could still only use words he had heard.

Knuckles, interested in Emerl's connection to the Chaos Emeralds and doubting that Sonic could make him into a great warrior, later decided to spend some time with him. Upon arriving at Tails' lab, the two friends saw on TV that two Emerl-looking robots were out stealing jewelry. Knuckles decided to do something about it, and took Emerl with him to destroy the copies. They ran into Gamma, and beat him yet again. Rouge then appeared, and told them that Eggman was trying to get his hands on Emerl. Knuckles and Emerl then proceeded to Night Babylon, where they asked around to where the fake Emerls were. However, Emerl was mistaken for one of the robber robots and they were forced to fight several guard robots. Eventually they ended up in Rouge's club, where they fought Rouge herself. After that, they quickly found two Phi robots, destroyed them, and took their shards. Rouge thanked them for stopping the Phis from attacking her club, and gave them her own Emerald shard. The echidna and the robot then continued their search and ended up destroying two more robots and creating a fourth Emerald for Emerl.

On one of her usual trips searching for Sonic, Amy again scared the blue hero away, and took it as a sign that he wanted her to take care of their "baby", Emerl. While Amy was overjoyed by Sonic's decision, Emerl ran off to fight two nearby Phi robots. Amy followed suit and they ended up with two new Emerald shards. Deciding that Sonic would be very impressed if she gave Emerl a new Chaos Emerald, Amy went on a search for new Phi robots. She first decided to train some, though. Amy and Emerl went to Amy's apartment, where Cream the Rabbit and Cheese the Chao temporarily lived. Amy then taught Emerl about boxercising, which Cream disliked. The trio fought for a while, until Emerl felt Chaos Emeralds nearby and ran off. Amy followed him to Night Babylon, where he found him insulting Rouge. After fighting the disdained bat, Amy started to explain only to be interrupted by two attacking Phi robots. After Amy and Emerl destroyed the robots and took their shards, Rouge gave them another shard as well, creating the fifth Chaos Emerald for Emerl to absorb.

Eggman finally decided to take matters into his own hands and captured Emerl, along with Cream, and took them to the Gimme Shelter. While trying to escape, Emerl destroyed four Phi robots and got their shards, but was stopped by the shard-powered Gamma, as Emerl stopped fighting since it made Cream sad. After watching Emerl getting constantly smacked around, Cream decided that fighting can be good if it is used to protect someone, and attacked Gamma. Along with Cream, Emerl managed to defeat the robot and take its shard as well, creating a sixth Chaos Emerald. As Eggman came there to check up on things, Cream and Emerl managed to trap him and escape.

Prior to the game, Shadow had been hearing voices. Upon investigating, he found the Gizoid in Gimme Shelter. Rouge, who was also there, explained that it was The Ultimate Being (Ultimate Lifeform in the western versions) and that it was a weapon just like Shadow had been. The duo was then attacked by guard robots. They fought back most of them, but Shadow got injured and Rouge had to drag him home. Shadow had some disturbing nightmares, and decided that the weapon of mass destruction, the Gizoid, had to be destroyed before it got all the Chaos Emeralds. After a few attempts to take the robot by force (mentioned above), Shadow decided to simply tell Sonic his point of view. Rouge told him that Emerl could be made into a peaceful being by giving him all the Chaos Emeralds and saying "bring hope to humanity". Shadow then did just that, and instead of becoming an insane world-destroyer, Emerl continued to be his usual self. Impressed by the ultimate being, Shadow fought Emerl and won. He then decided to go all-out, and let Emerl train against all of his friends before fighting Shadow again, this time winning. After this Emerl got the chance to fights his friends again, except Sonic was nowhere to be found. Upon returning to Shadow, he also found Sonic, who wanted to fight Emerl again, this time with Shadow. Emerl managed to defeat the two hedgehogs, and started living a normal life with his friends.

That didn't last long, however, as Eggman had finished his Final Egg Blaster, placed on his newly rebuilt Death Egg, and threatened the Earth with it. Using a teleportation device built by Tails, Emerl travelled to the Death Egg and defeated Eggman. Thinking that the doctor had learned his lesson, Emerl turned away to leave, as suddenly Eggman fired the Final Egg Blaster on some nearby stars, destroying them. This overwhelming power activated a part of Emerl's program that his friends did not know about: if the Gizoid is shown ultimate power, it will break its old Link to form a new one with the owner of the power. However, it did not go as Eggman had planned, as the old Link breaking also included Emerl's personality to be deleted, and allowed him to turn into the weapon of mass destruction that he was built to be. Emerl spouted out some binary (it should be noted that the binary doesn't actually mean anything), knocked Eggman out, and aimed the Final Egg Blaster at Earth. Thinking that Emerl could be stopped by negating the energy of the Chaos Emeralds, Sonic brought the Master Emerald to the Death Egg. However, Emerl got annoyed by the light the large jewel produced, and shattered it. Meanwhile, Tails had devised a theory that Emerl's initial programming could be reversed again if he took enough damage, but this would most likely destroy Emerl's body. As it was the only way out, Sonic attacked Emerl, and succeeded with the plan. As Emerl started to break down, he reverted to his old personality and thanked Sonic for all the good times they had together. Sonic desperately tried to save his friend, but Emerl disappeared in a flash of light, leaving only the shards of the Chaos Emeralds behind.


  • Like Metal Sonic, Emerl has the ability to copy abilities from other beings and machines.
  • Like Chaos, Emerl gets stronger (and smarter) with each Chaos Emerald he gains.
  • In Sonic X, Emerl cannot copy more than one being's abilities at a time, and takes a certain amount of time to do so. However, The Emerl in Sonic Battle can equip abilities from several characters simultaneously.
  • In Sonic X, Emerl is equipped with a jetpack, and this is why he does not need to copy flight ability. Emerl had this in the game, but he didn't use it.


Emerl has no original personality: His tendency to copy all things he sees carries over into his personality and intelligence, which grows based on the number of Chaos Emeralds he has absorbed. This leads to interesting results, as he initially is childlike and is only capable of repeating a phrase he has only just heard (and he usually repeats it twice). As the game progresses, he develops a sort of amalgam identity from every other character, incorporating each of their traits into himself and bringing them together. Despite this, he is said to be most similar to Sonic (which stands to reason, seeing as Emerl formed a bond with him).

Emerl also develops minor bonds with the people he meets: These are not true bonds, as with Sonic, but personal ones of friendship. For example, he refers to Amy as "Mom" because she instructed him to refer to her as his mother (She is under the assumption that Emerl is Sonic's practice "baby" for their future--a patently erroneous assumption no one has the courage to dispel). He sees Knuckles as a good friend and sparring buddy, Tails as a surrogate brother of sorts, Cream as a little sister, Rouge as a sort of Aunt, and so on and so forth. His relationship with Shadow is more one of professional acquaintance (thanks largely to Shadow's recalcitrance and annoyance at Emerl's similarity to Sonic).

Emerl does have one major flaw: He will immediately form a bond with the person who shows him the greatest power. Shadow attempted to circumvent this by using a passcode that should have disabled the needed programming, but was apparently unsuccessful. This is exhibited when Doctor Eggman fires his newly reconstructed "Final Egg Blaster," a weapon of ruinous power, far superior to Space Colony Ark's Eclipse Cannon. This completely overwhelms Emerl and his personality, reverting him to his "Gizoid" state and forcing him to attempt to use his newly acquired power to destroy the Earth itself, much to the surprise and dismay of the Doctor, who did not intend for that result. This leads to his destruction at the hands of Sonic, which ends the game.

E-121 PhiEdit

Main article: E-121 Phi

E-121 Phis are copies of the robot Emerl used by Eggman. They are small silver robots with powerful weaponry. There were 14 Phis which each copied an ability of Sonic and friends. They were all powered by Chaos Emerald Shards and because of this Emerl destroyed them in order to get all the Chaos Emeralds.




Gemerl appeared in the Game Boy Advance game Sonic Advance 3. According to the official Japanese website of Sonic Advance 3, Dr. Eggman created Gemerl from Emerl's "data", but he most likely used some of Emerl's remaining parts. Gemerl had the ability to "merge" with other machines, and as such co-piloted all of Eggman's boss vehicles. He was also fought by himself in Act 3 of the "Sunset Hill", "Toy Kingdom", and "Cyber Track" stages, and as a miniboss in the "Route 99" and "Alter Emerald" stages. Unlike Emerl, Gemerl often uses his jetpack, either to fly or to tackle enemies. He can also teleport, fire barrages of missiles, and create a red energy shield around himself. Fans frequently call him "Gemel" or "G-mel", though there is no official English name.

If the player collects all of the Chaos Emeralds in the game, Gemerl becomes extra final boss of the game and uses the power of the Chaos Emeralds to transform into a powerful orb-shaped machine. The Chaos Emeralds caused Gemerl to become destructive, like the last time he had encountered the seven Emeralds together back in Sonic Battle as Emerl, and Gemerl betrays Eggman by throwing him at Sonic before escaping. Sonic turns into Super Sonic and teams up with Eggman to defeat Gemerl during the final boss stage, which is named "Nonagression".

This round form of Gemerl had four extendable arms with claw-like hands that could fire energy beams and missiles. His only weak point is his gem, which is protected and impossible to harm unless Super Sonic charges Eggman with energy and throws him at Gemerl. It is believed that this form is similar to the form that Emerl became when he "destroyed" the fourth ancient civilization mentioned in Sonic Battle.

After Gemerl is defeated, Cream and her mother, Vanilla, find his broken body on the beach, and take him to Tails. Tails then proceeds to repair Gemerl and delete all of Emerl's destructive data, leaving his normal data. Gemerl then remembers Cream, becomes her friend again, and is seen playing with her at the end of the game. Notably, the music that plays during the Nonagression stage is a remix of Emerl's theme from Sonic Battle.

In Sonic Battle, if you set Emerl's colors to E-102 color 1, Rouge color 2, and Knuckles color 3, Emerl will look like Gemerl

Other mediaEdit

Sonic X (cartoon)Edit

In the English dub of the TV series Sonic X, Emerl was called "Emel" because of a mistranslated R (oddly, he is still called Emerl in the Spanish dub). An ancient robot recovered by Dr. Eggman, Emerl is activated by Bokkun to help him distract Sonic while the Doctor is being broken out of prison. With the ability to copy the attacks of anyone he sees, Emerl is a formidable opponent. He joins Sonic and co., particularly becoming friendly with Cream the Rabbit. As he watches Sonic and the gang in action, he copies their moves.

Like several other characters, Emerl enters into a fighting tournament for the red Chaos Emerald. After winning, Emerl absorbs the Emerald. His old programming, wiped because of his defeat at Sonic's hand, is restored, and he sets about destroying the area. Despite the efforts of Sonic, Knuckles, Rouge, Tails, and Amy, Emerl is unstoppable. This is because, since he can duplicate all their moves, he can match anything they throw at him.

Finally, Cream the Rabbit and Cheese defeat Emerl by working together, alternating attack patterns too fast for Emerl to copy. Overcome, Emerl fell into the ocean and sunk. He and Cream became good friends while he was around, and it broke her heart to attack him. The last thing that Emerl captured was Cream and Cheese crying, and he learned how to cry, moments before exploding.

Sonic X (comic)Edit

In the ongoing Sonic X comic, Emerl appears to have mistaken Dr. Eggman for his grandfather Gerald Robotnik, and considers him to be his master. Emerl is also seeking his place in the world. He was disassembled by Eggman by issue 11.


In Sonic Chronicles: The Dark Brotherhood, it was revealed that Emerl was created as part of a Gizoid army created by the Nocturnus Tribe, he is said to be the most powerful Gizoid created, but was left behind when the Nocturnus clan was pulled into the Twilight cage. The gizoids in the game appear to bear some resemblance to G-mel (but without the "fins" on the arms) but with Emerl's color scheme, and they hold an usual weapon in their right hand. The Gizoids fight using attacks from other characters. There are also two prefect Gizoids known as Charyb and Scylla who live in Nocturne and guard two chaos emeralds. Both have a different horn design from other Gizoids and are coloured blue and a red-brown color respectively. Charyb deals water based attacks and Scylla deals fire based attacks. There are also two bigger Gizoids called Gizoid Guardians. These two appear to be the guardians of Ix and assist him in the second battle in Nocturne.


  • In the Japanese version of Sonic Battle, all of Emerl's "spoken" text is written in katakana, a Japanese alphabet that is generally used for names and loanwords, instead of the ordinary hiragana.
  • Emerl somewhat resembles Pulseman, the main character from the Pulseman game produced by Game Freak for the Sega Mega Drive released only in Japan. The only difference is that Emerl looks like Pulseman without his synthetic skin and armor, which makes him look as if he was Pulseman's robotic skeleton.
  • It is worth noting that when Emerl gains the ability to speak, he addresses Sonic as "Metal", hinting that he has met (or at least heard of) Metal Sonic
  • Charyb and Scylla are named after the mythological Greek monsters Charybdis and Scylla respectively. Charybdis was a giant who lay underwater and caused whirlpools when he inhales through his nose. Scylla was a dragon-like beast who ambushed sailors at the Pass of Scylla and Charybdis. Odysseus met with both Charybdis and Scylla.
  • In Sonic Chronicles: The Dark Brotherhood, Nestor the Echidna makes references to a gizoid he befriended prior to the Nocturnus Tribe being pulled into the Twilight Cage, and says this gizoid must not have been transported along with them. It's incredibly likely said gizoid is the one that would later be known as Emerl.
  • It is notable that Emerl has ended up dying similar deaths every time he appears in a Sonic-related media: Being dismantled and being blown up twice.
  • Emerl's name is based on Emerald, referring to his power to absorb Chaos Emeralds.
  • Due to having Gizoids appearing in Sonic Chronicles: The Dark Brotherhood, it is unknown if Emerl OR Gemerl will reappear in the game's sequel since the first mostly focused on the Nocturnus Tribe and the Gizoids.
