Doom sucks arse.
Magneto is quite possibly the best villain ever.

Mongul is better than Thanos because he wiped out a whole city and Thanos is just a weak arse Darkseid clone anyway.

Black Manta is gay and has a gay costume.
Fuck it, that could be said of any Aquaman villain.

Joker is overexposed and overrated.

Spiderman villains tend to be shit, as do Flash villains.
