Time for some Samus speculation. :kirby:
Samus in her latest Smash incarnation is interesting to to talk about, because she's had some pretty notable changes over the past couple games. In Brawl, her speed was significantly reduced from that of the original Smash and Melee while in Power Suit form, and her Final Smash would destroy her Power Suit, making her Zero Suit Samus, a form much less powerful, but with a crapton more speed and all-new moves. And, of course, Zero Suit Samus's Final Smash reformed her Power Suit.
Now, in Smash Bros. 4 -- I'm aware the actual names are "for 3DS" and "for Wii U", but I'd much rather not type all that out -- she's been given the Other M treatment for her look with a few minor alterations, and her gameplay style seems to have been sped up, although whether it's straight-up original Smash/Melee speed or a mix between them and Brawl is not quite clear yet, what with the gameplay footage shown of her being all of about 5 seconds. We did see her use her Final Smash, but we didn't see her Power Suit break from it, since the footage jumped over to Villager before we could, but I can't see developers removing Zero Suit Samus. I can't confirm that she'll return, but until we get further word, I'll be acting under the assumption that she'll be making another appearance.
However, it's a mystery as to whether or not the suit will indeed break because of this. Will we be seeing Zero Suit Samus as her own character, or will it remain the same as in Brawl? Will we see a sort of Zelda/Shiek thing going on where Samus is now given the ability to switch at any time? It's a possible change. After all,
off-screen footage of a match at the showfloor of Nintendo's E3 booth has revealed that Mario has been given the F.L.U.D.D. from Super Mario Sunshine, at least in the Wii U version. (Warning, the live announcer in that video is annoying as mess.) Whatever the case, it's interesting to be able to speculate about this sort of thing. It's not something I would have been expected to be speculatable (if that's even a word).
That seems to be about it for now, at least involving the major stuff. If I've missed out on anything, let me know.
