Most of these tier lists sucks in my opinion. Snake can't be god tier. Though it sucks, I will list some requirements of the Top tier list.
Good Projectile, can combo well, has decent knock back, quick with curtain things(attacks with little lage, running speed) and of course, edgeguarding with many techniques.
Like I said it sucks.
For these requirements, you have, Pikachu, Fox, Falco, Sheik, and Pit.
Requirements for High.
Almost as good as the top but maybe a little slower or worse in anyway that still has them a little similar.
I.C., Toon Link, Zelda, Lucario, Squirtle, Diddy, Peach(wtf still), Marth, Metaknight, Wolf, ROB, and Luigi.
Middle is decent overall.
Has Olimar, Bulbisaur, Charizard, Dedede, Kirby, Lucas, Mario, Ness, and Samus(really...wtf Nerf).-_-'
Low is near useless.
Low is DK, Sonic, Bowser, Ike, Yoshi, Mr. Game & Watch(maybe higher), Jigglypuff(just too light), Link, and Captain Falcon.
Bottom useless period.
(WTF...aren't there anyone left -_-' - Nooo! What about Ganondo...he is better than some like bowser overall and has a gannycide).
I don't know why people hate Captain Falcon or Ganondorf. Use the Uairs and forward B and you will win. Plus great DI doing the up B. I never lost with him before. Samus is even worse with the nerfs and bombs not exploding really. Harder bombjumps, no attacks after a bomb jump until frames end and weak as hell nair...with decent knock back after about 200% damage really. But she is still good. Zero Suit Samus is middle. Good at comboing. Captain isn't fast anymore. Ganondorf is even slower. Link has slower dash, but faster running speed. Toon Link has a boomerang with his body high hitbox going out. Link's fair was nerf'd.
Tiers are getting really crappy. The game was made with a way of eliminating the tiers almost completely, but as a result, made many good characters bad and terrible characters worse. Really. Plus the list I made is crappy as Hell.
Thanks for reading. -_-'(depressed)
