Gmerl

Gmerl is a robot that appeared in the game 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, such as Eggman's boss vehicles. Like Emerl, Gemerl became destabilized in the presence of all seven Chaos Emeralds.
