Well, there's this girl from the Mario games with a different color dress than Peach. She wasn't introduced until the later games but now she's in, like, every spin-off.

…Nah, that's not right.

There's also this dude from the newest Fire Emblem who wields a sword and has a really big part in the story.

…Nah, that's not right either.

I remember a third party character with brown hair and a bandana. He seemed a bit more realistic than the others both in terms of appearance and fighting style.

…Nah, that's not right.
