You literally transmute matter at will, you do not need to fight Killcannon just turn his robot arm into cheese or something. Your nemesis is a villain that you do not need to consider the whole cannot effect living tissue thing for even a second. That is all.
Ngl, this is why I don’t like Eve’s powers conceptually. It’s Overpowered in the hands of someone with half a brain.
Which means having a character too stupid to use their powers in creative ways and to potential is both frustrating and just plain immersion breaking.
