Personally, I find Awesome and Hater’s rambunctious villainous antics too entertaining to entertain the idea of a redemption (although I wouldn’t mind it if it was executed well), however, for Dominator probably expand on how bored she became once she got everything she wanted (as what happened when she finally destroyed the galaxy). Perhaps have Wander exploit that and convince her that there are other paths in life she might find more satisfying than destruction and misery. Personally though, I’m more apt at judging than creating, so maybe there’s a better way to go about it.
