Gemerl[2] (ジーメル[1] Jīmeru?, lit. "G-merl"), is a character that appears in the Sonic the Hedgehog series. He is a robot created by Dr. Eggman from Emerl's data,[3] making him a revised version of his predecessor. Gemerl once aided the doctor in his attempts to stop Sonic and his friends from foiling one of his plans, but wound up betraying Eggman to cause mayhem. After his defeat, he was reprogrammed in the image of his predecessor.


Gemerl is a humanoid, mostly black, robot. He possesses five-fingered gray hands and feet in the shape of shoes with black soles and yellow lines around them. His upper arms, abdomen and thighs are gray, and he has spherical black joints as shoulders and pelvis-leg joints. He also has relatively thick armor around his forearms and lower legs, (each one possessing yellow cuffs), fin-like yellow kneecaps, fin-like yellow objects on his forearms, and some kind of jetpack on his back. On his chest, he has three gray circles. Lastly, he possesses a spherical head with a gray mouth plate, blue eyes with red rims, gray caps resembling ears, and a curved yellow horn with points sticking out from the sides and a blue eye in the center on his forehead.



Gemerl was created by Dr. Eggman sometime after Emerl's destruction to be the ultimate fighting robot.[4] To create him, Eggman used Emerl's data.[3]

Sonic Advance 3

When Eggman broke the earth with Chaos Control to conquer each piece, Gemerl helped Eggman to prevent Sonic the Hedgehog and his friends from fixing the planet. Gemerl kept intercepting the heroes, but was defeated each time and had to retreat. He would also join Eggman in his mechs, whenever the doctor confronted Sonic and his friends, only to be beaten and flee with Eggman. Eventually, Gemerl made a final stance at the Altar Emerald with Eggman, but they lost once more. As Sonic and his friends restored the earth, Gemerl and Eggman tried to escape when Gemerl's battle damage made him unstable. He then stole the Chaos Emeralds from Sonic, which he used to transform into Ultimate Gemerl. Gemerl then betrayed Eggman and escaped. In space, however, Gemerl was confronted by Super Sonic and Eggman who defeated him.

Reverting back to normal in a large explosion, Gemerl landed on earth where his broken body flushed up on a beach. Found by Cream and Vanilla, he was taken to Tails who repaired Gemerl and reprogrammed him into the kind-hearted Gizoid he was based on. Gemerl soon after befriended Cream and came to live with her and Vanilla.

Other game appearances

Sonic Mega Collection

In Sonic Mega Collection, Gemerl makes a cameo appearance as a piece of artwork.

Sonic Generations

In the Nintendo 3DS version of Sonic Generations, Gemerl appears on an unlockable bonus artwork from Sonic Advance 3 in the Collection Room.


Initially, Gemerl lacked any kind of true personality, though he would display some of Emerl's traits over time, supposedly due to containing his data. When serving Eggman, Gemerl behaved as an emotionless machine and was completely obedient and unwaveringly loyal to the doctor. After receiving damage at Altar Emerald, however, Gemerl gained a sense of free will and acted similarly to Emerl under his original programming, becoming aggressive, hostile and bent on causing destruction. After being rebuilt by Tails, Gemerl became a kind-hearted, gentle and supportive robot, much like Emerl near the end of his life.

Powers and abilities

Being created as the ultimate fighting robot, Gemerl is built for combat. Due to also being based on Emerl's data, which was loaded with battle information, he presumably possesses high level fighting skills.

Gemerl possesses a jetpack on his back, allowing him to either fly through the air, perform powerful midair spin attacks or move along the ground at super speed. He is also quite durable, being able to withstand being blown up and still continue to function. Additionally, he can teleport, fire barrages of missiles, and create a red energy shield around himself.

Gemerl also has the ability to "merge" with other machines and, as such, co-piloted all of Eggman's battle mech vehicles.


Ultimate Gemerl

Ultimate Gemerl, from Sonic Advance 3.

With the seven Chaos Emeralds, Gemerl can assume a super transformation into a much stronger form named Ultimate Gemerl. This form has four extendable arms with claw-like hands that can fire freezing energy beams and launch missiles. Its only weak spot is its blue gem, which is protected and impossible to harm unless Super Sonic charges Eggman's Egg Mobile with energy and throws him at Ultimate Gemerl.




In other media

Archie Comics

Main article: Gemerl (Archie)

Gemerl, from Sonic the Hedgehog #273.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Gemerl has a personality similar to that of Shard the Metal Sonic. Much like in the games, Gemerl was originally a weapon-based android created by Dr. Eggman, but was converted to good after his betrayal of Eggman and came to live peacefully with Cream. Currently, he acts as Mobotropolis' protector during the Freedom Fighters' absences.

IDW Publishing

Main article: Gemerl (IDW)

Gemerl, from Sonic the Hedgehog #18.

In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, Gemerl lives with Cream and her family in Floral Forest Village. In this media, his past is virtually identical to his game counterpart's, up until after the events of Sonic Forces. During the Metal Virus pandemic, he defended his village from Zombots. He then regrouped with his family to Restoration HQ, accompanied by Cream and Vanilla. He later retreated to Angel Island with Cream, and in Sunset City he helped Cream defeat Zeena and reclaim her Chaos Emerald. However, Cream got infected with the Metal Virus in the process, so Gemerl stayed by her side until she was cured and reunited her with Vanilla. Some time later, Gemerl accompanied Cream to White Park Zone, where they, along with Amy and Rouge worked to get spare parts for a damaged Omega. The many adventures left Gemerl badly damaged, but he was eventually repaired by Tails.


  • Gemerl's artwork pose is the same pose that Emerl does in one of his Sonic Battle artworks. This is presumably to further enforce how Gemerl is a copy of Emerl.
    • Additionally, his fighting pose when he stands still is exactly the same as Sonic's in Sonic Battle, which Emerl had copied from Sonic.
  • Gemerl's theme is a remix of the themes of Phi and Emerl, as well as excerpts from Colosseum's music, in Sonic Battle.
