Rosalina's cool and all but Palutena. She'll have to concede with the title of best mario waifu sorry.
Um, what? Palutena is from Kid Icarus, which doesn't take place in the Mario universe. So she can't even be a "mario" waifu to begin with.
That aside, Rosalina existing has this strange effect. If they show her making an appearance in a game, it suddenly takes me forever to decide whether or not I want it. Which is interesting, considering I'm not "obsessed" with any character in general.
