Why can't the fast comboer/rush down charecter be male?
Could be, but usually that's reserved for young males (EX: Young Link approaches it.)
Basically, because of stereotypes.
And why couldn't Chrom be rushdown and fast?
Speed, defense and strength are his highest base stats in Awakening.
Chrom's an adult male, simply put. Nimbleness and flexibility (key components of rushdown/combo/speed characters) generally aren't associated with adult males like it is with younger males or females in general.
I really don't think base stats in games have very much relevance to Smash unless it's truly defining (EX: Pikachu is an electric type, which is the type very well-known specifically for speed, hence Pikachu is somewhat fast.)
Except Chrom has other possibilities. He has a shield at his disposal, and as seen in various Awakening cutscenes does things that Marth doesn't. He does lots of spinning and what have you.
Just because a character has a sword doesn't mean he's automatically going to be the same as another character. That's a bit foolish thinking at this point. We've seen character after character get in with a unique moveset. If Chrom gets in, which I'm almost certain he is, he's going to have something unique to him.
Not to mention, Sakurai made Little Mac unique. Yet all he does is punch. This can easily be done to Chrom. It's not like it's impossible for him to be unique. Thinking it IS impossible is getting ahead of ourselves.
As others have said, Chrom could just as easily be the rush down character anyway, so there's absolutely no reason to think he's out of the picture.
1. Yes, he has great potential for moveset diversity, which is fortunate for him.
2. If a character has a sword, he is going to share more in common with other sword characters, and thus have less means to make themselves unique; they certainly can still make themselves unique, but it becomes more difficult. Thankfully, I never thought "sword=same" by default, that's a hyperbolic strawman.
3. Little Mac being a "punch-only boxer" is unique in and of itself. His difficulty was having a diverse moveset, but not having a unique niche, so this is a false comparison. I don't think it's impossible, but I think it's safe to say "he's not getting in." It's a wager.
Several characters already share similar niches (Fox and Falco, Ness and Lucas), so this should not affect Chrom in the slightest.
I think it's very possible that a Star Fox character will get cut, and quite likely that a mother character will get cut. To say it "doesn't affect in the slightest" is kinda unrealistic; the question is how much it will affect him, as Sakurai has made it clear that these things matter. Similarly, I think the existence of other characters already overlapping niches actually hurts Chroms chances, because the less you'd do it, the better it would be. Do it more, you're incentivized to not do it again.
I also severely doubt the likelihood of a female
Fire Emblem newcomer, unless it is the gender-interchangeable Avatar (which I would favorably prefer instead of Chrom, although I do not expect inclusion). All that is leftover is Anna (another character I would prefer), a brazen wildcard whose importance lies only within the role of a representational mascot, which cannot nearly compare to Chrom, a main protagonist of a considerably successful title.
Anna is one of my "wildcard" guesses for a final roster.
First of all, why does this "fast/combo/rush-down" character have to be female? Secondly, why can't Chrom?
Answered above.
Popping out of the thread; it still feels too hostile to me. Granted, it's nowhere near as flagrant as it was before the thread was re-made, but it still scares me off.
