I think a thing people are forgetting tho is like its not like anyone is truly out of left field completely in smash outside of like maybe Cloud, but hes iconic enough to justify his inclusion due to his mark on gaming as a whole. Even the characters that people call "wtf picks" still have some p good reasons as to why they are in.
Ironically the only exception to this at all is actually
back in smash 4 lmfao. He was honestly the most "wtf" character in that game. The rest of the newcomers in every smash game all make sense logically and in the greater scheme of nintendo and video games as a whole.
Also its not some rule that we need a wtf pick or a retro pick every game. Or a new poke rep, or whatever. Thats just fan rules weve created at this point. So dont be super shocked if we might not get all of these fan made choices that we seem to be convinced of getting.
