Description from original post (created 2012-09-17 18:20):
Gemerl from Sonic Advance 3, a robot based off of Emerl from Sonic Battle, made by 'Botnik. Kinda like an upgraded Phi robot (also a Badnik from Battle), this guy is more of a mini-boss, often showing up before Eggman to rustle you up a little. After beating Eggman at the very end of SA3, Gemerl decides to go rogue, and is subsequently defeated by Sonic, the gang, and Eggman. He is seen to explode, and at the end of the credits reel, he is seen found by Cream, repaired by tails, and he turns into an Emerl-like character. More info on Him at your wiki of choice.
