Haven't seen enough of Arc V to say anything there with Yuuko, and Seiji is nothing like Juudai/Jaden, but Cure Fortune, Princess, and Lovely's cosplays are surprisingly fitting.
Fortune/Yuusei - Both try to be serious, but it just doesn't work (it may have been a better season than I expected but "Duel Monsters on motorcycles" still makes me laugh, and Fortune trying to be the "mysterious sempai with a tragic past" is too funny).
Princess/Yuuma - Both are whiny, obnoxious (and frequently incompetent) amateurs. Here's hoping Hime doesn't stay as annoying as Yuuma did throughout Zexal.
Lovely/Yami - Almost didn't think they matched, but then I remembered just how brutal Yami used to be in the beginning of the manga despite Yuugi himself being so gentle, and how utterly vicious Lovely is despite Megumi constantly preaching about love, and I finally saw the connection.
