Trivially, Palutena. But I think she's basically a given on any list of characters that get noticeably better in customs.So who do we think are the top of the customs meta right now? What characters do notably better here than their default counterparts?
I'd also nominate Wii Fit Trainer, Ganondorf, Duck Hunt, and Samus as contenders for that list.
Note that this is just "characters that do better" not "top tier". I have no idea who's top tier in customs, but I'd actually expect it to be pretty similar to default. There isn't that much shuffling going on.
