Suggested by Destroyer Thumbelina has always been an interesting character. It’s great that she’s a crimefighter but the ability to turn small never really seems like a good thing. At least for Ant Man he keeps his relative strength but that isn’t quite the case for her. So Thumbelina’s best bet is actually not to use her powers. Either way that won’t be enough to win though although it may at least buy her a bit of time. At the end of the day I think that’s all she can really hope for here. Pinkie Pie wins.
