From left to right, my concepts for villains.
Fire power, suit would probably light up like charcoals when powers are active. Very boisterous personality, like if Mettaton X and Maleficent had a child.
Ice: Can make ice take many shapes, (Can beseen creating an ice dragon) cold, bleak personality.
Ice/Crystal: Flashy/Showy, Probably has a garden of crystallized victims. A loose cannon.
Invisibility: NGL he’s pretty but that’s the only thing he’s got going for him. Too bad his power is invisibility. Some men just want to watch the world burn.
Mech+Pilot: Does “Kick the shit out of your adversaries in a big robot” count as a power?
My current Bias is on The first 3.
