Mecha "M" Robotnik

Mecha Robotnik (3236-3237), or M for short, is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She was the robotic "daughter" of Dr. Eggman and sister of A.D.A.M.. Loyal only to Eggman, Mecha was as cold and emotionless as most of his creations—most of the time. She only showed emotion on a handful of occasions, usually when Eggman was threatened. At these times, she became extremely angry and volatile. Once A.D.A.M. gained self-awareness and started sabotaging Eggman's operation, Eggman became paranoid and ordered M to self-destruct, an order she obeyed.
