uh, i don't know when you grew up but everyone and their dog in my neighborhood knew who kirby was before smash bros came out. kirby was a very popular nintendo character and he's not really a character i'd list as "B" tier. everyone also knew who fox mccloud was since you know... star fox snes and SF64, one of the earliest games released. samus was also well know.
come to think of it, the only two that could be considered obscure at the time were 1) C.Falcon, and that's a stretch to call him obscure, and 2) Ness, which is fair to call him relatively obscure
so what i guess im trying to say, and don't take this the wrong way, but you're dumb
