Mecha Knuckles


 * For the earlier robotic version of Knuckles, see Metal Knuckles.

Mecha Knuckles (メカ ナックルズ), a robotic version of Knuckles the Echidna.

Sonic Advance
Mecha Knuckles was the boss of Angel Island Zone in Sonic Advance. He had virtually every move Knuckles had, plus the ability to fire rockets from his mouth in his second form. He looks like a magenta Knuckles with yellow gloves at first, but after being struck four times his "armor" will fall off, revealing a metallic echidna with glowing red eyes underneath. After being attacked another four times, the robot explodes. The current player character seems slightly stunned when seeing Mecha Knuckles for the first time, but Knuckles' reaction is comically over-the-top when he sees his robotic doppelganger.

Archie Comics
In the Archie Sonic the Hedgehog comics, the Freedom Fighters were once forced to roboticize Knuckles to combat a roboticized version of Sonic, called "Mecha Sonic" and the robotic Knuckles was dubbed "Mecha Knuckles". After a drawn out battle, both combatants were eventually restored to normal. (MMS)
