Hey guys guess what: 
Any character they want to work in Smash would work in Smash. 
Snake was hardly the ideal character, but it works. 
Kirby has Jigglypuff was hardly an ideal character, but he works. 
Donkey Kong never did anything but run and jump, but he works. 
Ice Climbers? I mean seriously. 
It really doesn't "how well" anyone would work. If they WANT to put them in the game, they will, and it'll work. 
Also: Richter Belmonte is effing broke AT LIFE. 
Most Belmontes = run, whip, jump. 
Ricther = DASH, SLIDE, RAZOR THING, UPPERCUT, RAIN HOLY WATER, SHOOT GIANT CROSS, OPEN GIANT BIBLE... 
I mean the dude is cool and all, but seriously....broke. Chris & Trevor beat Dracula without ANY of that shit.
