I see your topic is being reposted on GameFAQs. Yay!
EDIT: Rereading it as you post, commentry:
I'm surprised there is no mention of the Torchic Pokeball in the Blaziken section.
Unfortunately for Kumatora, Lucas has taken Ness’s moveset, which means that she would have to be a clone of Lucas in order to be playable. I expect Kumatora to show up either as an Assist Trophy or a regular trophy.
I'm not sure I actually agree with this. Ness had PK moves he didn't have originally, what's stopping them from doing the same here?
The Bulborb from Pikmin has also been confirmed as a trophy.
Irrelevant, but someone pointed out to me that a Fiery Blowhog trophy was in the Coin Launcher update.
I kind of think you have the Tom Nook/K.K thing backwards. People have proven that other fighting games, like Street Fighter, simply switch characters when they're playing with that character in an arena where they're normally in the background. Also, by thaat logic, it'd be impossible for two players to select Mario, as then you'd have two of the same character on the stage.
Mach Rider had a Melee trophy?
And that's all.
I just finished reposting it.
Also, I don't think Torchic really affects Blaziken's chances. I still think the most Blaziken has to hope for is Pokeball status. Besides, Pikachu being playable didn't stop Pichu from joining the roster.
Also, I expect that if Ness does return he will either be Luigi-fied clone of Lucas, or have a moveset that is more true to the abilities that he had in EarthBound. Also, recently there have been rumors to suggest that Ness may be returning as a playable character (ChaosZero).
Also, there is a reason why I have not ruled out an Animal Crossing character, and that is because Sakurai does not play by the rules.
And finally, yes there is a trophy of Mach Rider in Melee. Mach Rider has also been recently confirmed to be a sticker in Brawl.
