Okay trying something a little different with these last 3 because Superman, the Justice League and Batman have big rouges galleries. Again, say who you think the most underrated villain is for the character or team in the title.
Silver Banshee. Access to the dead, magic, and loud noises. She’s got a high potential to be much MUCH worse if someone wrote her that way.
And if my man Toyman ever actually does get to kill any children he’ll be much worse and other people will finally realize just how underrated he is 😈.
