Powers and abilities

Gemerl (ジーメル Jīmeru?), also known as G-merl,[1] is one of the main antagonists in Sonic Advance 3. He is a robot created by Dr. Eggman from the data from Emerl, essentially making him a reincarnation of the deceased Gizoid. When Eggman broke the earth with Chaos Control, Gemerl aided the doctor in his attempts to stop Sonic and his friends from fixing the planet. Eventually, Gemerl betrayed Eggman to cause mayhem, but was defeated and later reprogrammed in the image of his predecessor.


Gemerl bears a great deal of resemblance to (and derives his name from) Emerl, the prototype Nocturnus Clan Gizoid whose development forms the core of Sonic Battle's story, due to being built from Emerl's data. Unlike its incarnation Emerl however, Gemerl has a black, yellow, and grey color scheme and red and blue eyes and has several sharp fin-like objects attached to his arms, legs and head.


Gemerl was created by Dr. Eggman sometime between the events of Sonic Battle and the beginning of Sonic Advance 3 to be the ultimate fighting robot by using Emerl's data as a basis for him.[2][3] This supposedly gave Gemerl some of Emerl's hardware and memories.

When Dr. Eggman broke the earth into seven pieces with Chaos Control so he could conquer each piece, Gemerl was deployed by the doctor to help him prevent Sonic the Hedgehog and his friends from undoing his work. During Sonic and his friends' adventure, Gemerl intercepted the heroes alone in Route 99, Sunset Hill, Toy Kingdom, and Cyber Track, but was defeated every time and had to retreat. He would also appear at Eggman's side whenever the doctor confronted Sonic and his friends personally, as a part of Eggman's mechs, but each time they were beaten and forced to retreat.

Eventually, Gemerl made a final stance at the Altar Emerald where he faced Sonic and his friends, but lost once more. He then joined Eggman in the Hyper EggRobo, but they were defeated again. With Sonic and his friends having restored the Earth, Gemerl and Eggman tried to escape when Gemerl's battle damage caused him to become unstable and destructive. He then flew at Sonic and stole the Chaos Emeralds from him, which he used to transform into Ultimate Gemerl. Gemerl then betrayed Eggman and escaped to cause havoc. In space, however, Gemerl was confronted by Super Sonic and Eggman, and faced them in battle.

In the ensuring battle, Gemerl was defeated and he reverted back to normal as he disappeared. Landing back on Earth, Gemerl's broken body eventually flushed up on a beach where he was found by Cream and Vanilla. He was then taken to Tails who repaired Gemerl and turned him back to the peaceful Gizoid he was based on. Remembering Cream from his past life, Gemerl became friends with her and he came to live with her and Vanilla.


Initially, Gemerl lacked any kind of true personality. However, supposedly by containing the data of Emerl, Gemerl displays many of the traits Emerl had. When serving Eggman, Gemerl behaved as an emotionless machine and was completely obedient and unwavering loyal to the doctor. After receiving battle damage at Altar Emerald, however, Gemerl gained a sense of free will and acted similar to Emerl under his original programming, becoming aggressive, hostile and bend on causing destruction. After being rebuild by Tails, Gemerl became kindhearted, gentle and supportive, much like Emerl over the course of Sonic Battle.

Powers and abilities

Being created as the ultimate fighting robot, Gemerl is build for combat. Due to also being based on Emerl's data, which is loaded with millennia worth of battle information, he presumably possesses a 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 blow 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 mech vehicles.

Super transformation

Main article: Ultimate Gemerl

Ultimate Gemerl

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.

Main article: Gemerl (Archie)

Gemerl is mentioned in the Archie Comics' Sonic the Hedgehog comic books and spin-offs. In this media, he is a friend of Cream the Rabbit and Vanilla the Rabbit in the timeline created by the Super Genesis Wave.





  • In Sonic Battle, if Emerl's colors are set to Tails Color 1, Rouge Color 2 and E-102 Color 3, Emerl will look like Gemerl.
  • 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.
  • Metal Sonic 3.0 looks similar to Gemerl because they share the same color palette. Coincidentally, they are both copies of other robots.
    • Additionally, the multiplayer Shadow Android has the same color palette as Gemerl. They are both copies of someone considered to be the ultimate life-form.
  • Gemerl's named is based off Emerl's. The difference is that a "G" is added before "emerl".
  • The History of Sonic the Hedgehog confirms his name to be Gemerl. This information is found in the trivia section for Sonic Battle.
