Toxic Touch: Midas's body consists of every toxic compound. His touch is capable of slowly melting away at structures and dissolving projectiles (such as arrows).
Toxic Immunity: Due to his physiology, Midas absorbs new toxins, rather than being adversely affected by them.
Genius: Midas appears to have a genius level intellect, previously working on a new way to treat toxic waste that would generate massive profits, as well as creating skin grafting circuitry.
Midas was once a scientist working on a bacterial strain that would be able to revolutionize the treatment of toxic waste. While demonstrating his findings, he encountered a woman who seduced him, but eventually turned out to be an eco-terrorist hoping to steal the formula. The terrorists botched the job, causing an explosion which killed them, but sent Midas screaming in flames. Burning alive, he leapt into a river of toxic waste, and emerged a monster entirely composed of it.
