[@Savo] so If I wanted to make a character who say... is an insane man with a cesspool of diseases and poisons, and has fused himself with various insectoid mutations with the goal of corrupting and destroying every last “perfect hero”, could I “hypothetically” do that?

You could, you could. Just play him well and try give him a good reason as to why he would want to destroy every last perfect hero in the world. Trust me, anything goes for the most part, like, almost anything ridiculous you can think of. Get your creative juices flowing, but try not to go overboard for the most part :P
