I actually suuuuuuper dislike Smash. ..... ^^; Buuuuut I do play with my friends because they're Smash nerds. =D
My favorite character is Lucina for many reasons- not only is she fast but she's a FE character and one I actually understand personally. I didn't play any of the FE games with Marth, Roy or Ike. Also, she's just awesome as a character.
The problem with Lucina is that her moves are boring. I hate their moves, the FE characters.... they're the most boring fighting game moves ever, more boring than Abel in Street Fighter. Like..... REALLY BORING. Not only that, but with Lucina I tend to become competitive, and Smash... it's a really frustrating game, so there's no way I could enjoy playing Lucina.
My main is Palutena. Palutena is a defensive character, and I'm a defensive fighter =P She's really slow though, so she forces me to think outside the box and not react the way I like to, which is fun. She also has ANGEL WING SMASHES AND THEY HAVE GREAT RANGE AND ARE SO FUN TO WATCH AND USE AND EVERYTHING AL:DRHAB:OJAK:LF
So yeah. Palutena and Lucina. I don't really care much for anyone else. ...... ^u^;;;
