Someone mentioned 1-1-1-1 Mii Brawler. Well it's time for an adventure in the weird fun facts I know about characters no one else pays attention to!
Fun Fact: Down throw into fair into grab reset into pummel into downthrow into fair reset into down throw into up air into back air can do 60% DAMAGE ON SHEIK FROM 0%. And yeah if you follow DI it can true combo from as far as any testing/matches I've had can tell. Works on a lot of fast fallers/heavies. This combo can do a lot of things too like you can go for dair and finish it early but try to spike off stage and other stuff.
Down throw into up b near the ledge at low percents can either spike (with you dieing with them) or you can just down throw - dair them. Down tilt can start combos and goes into up air until rather high percents and up tilt can start some things too.
The shotput can work for zoning and as a unique movement option, up b can spike folks with creative ledge trumping, side b is an okay punish and as far as I know down b is crap outside of a magical hard read at high percents to try and link into f-smash.
So you have a Marioish character that can actually put up some serious damage rather early and quickly. Here's the issue: KILLING WITH MII BRAWLER IS A [expletive deleted]
F-smash is SO laggy. Up smash takes a while to kill but as an odd tipper at the end of the move that could have edge guarding properties. side b can kill but it takes a strong punish at high percents. Outside of spikes if you're lucky there's maybe down smash which isn't horrible but isn't great either.
So in all honesty, we probably have a yoshi-esque character in a way where they have decent speed and can wrack up damage but as of now securing the kill is a pain. Plus with a rather linear recovery gimping is doable. To be honest I could still see Mii Brawler actually being high up there on the viable list but probably JUST at the very end.

Now onto the Mii I also know a lot about: Swordfighter. He's basically got 3 of the best moves he could want in 1-1-1-1: he's the Mii hurt the least by that arbitrary rule. I'll put it bluntly: if you think characters like Roy, Ike and Marth should be up there you probably should put Swordfighter right near them in a neat little bunch.
His buffs have been great for wracking on more damage, speed, and being a bit more safe. Fair can cancel into kill moves (and jab can too as a 50/50), his recovery has the sexy spike, up air can kill and combos out of throws very well, down air can poke shields, makes coming down nice, and can combo into footstool nicely for combos and/or off stage death. Bair can do nice damage and is rather fast/kill move. It can be comboed into too! Down tilt can combo into nair which can actually end up with grab resets at mid percents or you can just Fair for damage.
Hows about up air into up air TRUE COMBOS at kill percents? (is more complicated but is honestly landable for real)
He's a solid character with decent atributes, combos, and a disjoint. Don't count him out. He's nowheres near this whole (bottom character) thing people keep throwing him in. It's hard to cut the "worst character in the game" attitudes people got about him before ignoring he existed back in the early days

Mii Gunner: ask someone who knows more. I gotta toy with gunner more in 1-1-1-1.
