TMNT Legends Bio
A driven but largely incapable engineer, Stockman designs a robotic suit that he plans to use to take revenge. Utilizing a piece of tech to supercharge his suit, he becomes a near-unstoppable juggernaut of machinery.
Baxter Stockman is intentionally sprayed with mutagen by Shredder, becoming half man/half fly. With the power of flight, strength, and disgusting regurgitation skill, Stockman-Fly is a formidable enemy.
