First time I'm posting my roster as a fancy picture. Thoughts please, and I'll defend whatever you are unsure of. It's pretty safe though.
Wasn't sure Zelda warranted a big enough 5th rep in my opinion. They have all the major bases covered already.
Lucario I just have a bad feeling about, however, if a 5th rep for Pokemon makes it, I'd say it's Lucario.
Bowser Jr. has just made a bigger impact to Mario and has become increasingly popular and important to Mario as a whole. Toad really only has age on him in my opinion.
K. Rool over Dixie is personal preference. I think DK will only get 3 reps as well.
