Sunstorm

Fly too close to the sun and you'll get burned. Get too close to Sunstorm, and you'll be dissolved into a puddle of liquid scrap. The maniacal warrior's radiation-emitting armor has the power to melt the metal of nearby bots, disabling their circuits and scrambling their brain module in the process. Some might say this is a quirk of science - a glitch that triggered a reaction when Sunstorm was forged. Sunstorm himself would say it's something more: a gift from higher power that he must use on those who deserve to feel his wrath. That might be a little much, but do you really want to argue with him?
