I honestly feel like Dark Pit gets more hate than he deserves. Trying to avoid being bias as a Kid Icarus fan, his addition in the game as a clone isn't any worse than Dr. Mario or Lucina. The argument I'm seeing more people put up is that Dark Pit is just pit, but with a different color. In that case, Dr. Mario is just Mario with a coat on..but he doesn't seem to be getting the hate that Dark Pit has, and the Mario series already has more reps than the Kid Icarus series does (Understandable, with it being Nintendo's mascot franchise, but nevertheless) People go on about how Lucina is also welcome because some of them wanted her and because she's her own character in Awakening, but Dark Pit is his own character in Uprising as well. Yes, story wise, he's also a clone of Pit, but he has his own personality that makes him unique, just like Lucina has her own personality that makes her different from Marth.
Maybe I'm just ranting here, but it just irks me that Dark Pit has been put at the bottom and that Dr. Mario, who is ACTUALLY the character Mario himself, is getting by with less hatred and it feels as though it's just because he was in a Smash Bros. game in the past, making it more acceptable. I like the fact that Dark Pit is in the game because he's an awesome character, but I would have been just as fine with him not being there, same goes for Lucina. But even with that in mind, I feel as though many more people would be upset if Lucina hadn't made it in, even if they knew she would be a clone. Rant over, sorry about this.
