Was Lucario really that prominent in Gen IV? I beat Pearl when it came out and I hardly remembered the guy so his inclusion was really surprising to me. Was he really important in the anime or something?
yeah, anime.
Here is the list of characters that I would like to see
Kaptain Kool
Krystal (with Tricky Final Smash)
Isaac/Matthew/Felix/any Golden Sun characters
Takamaru
Laughing Dog
Ridley
Little Mac/King Hippo
King Fluff
Tom Nook
Geno (Shush, I love Mario RPG)
Shulk
Medusa/Magus (I know Sakurai might add one more character because he might grow a connection to the series.)
I think Sonic will return to fight again. Come on... Sonic and Mario are in same game for 4th time. I don't think they are going to stop yet. (I don't care if Sonic didn't make in or not. I loathe to play as him in regular brawl.)
I am not sure about Roy and Mewtwo returning. I can see Mewtwo as more likely because they ran out of time with Brawl. Roy and Mewtwo are two out of six characters that got left out.
I know I forget some characters but that's it for now.
