There is just so much wrong i don't know where to start:
Little Mac is bottom tier.
Luigi higher than Mario.
Mario bottom tier.
No signification of customs on or off.
Palutena neither in bottom tier nor top tier. She's one or the other, customs off or on.
Dark Pit above Pit.
G&W better than Palutena, Duck Hunt, ROB, Robin...
Where the hell is mid tier?
Rosalina 3rd -_-
Yoshi is high tier. Since top is top 8, he should be there.
Fox is low tier.
Zelda is the worst.
Sanic is second. Ok wtf
WFT is not getting her own tier at the bottom. She's not bad, simply the worst. She would be Brawl High tier, even the bottom tiers are good. She's just a victim of circumstance.
If she isn't gonna be garbage tier, then Mii Swordfighter is. He is the worst by a large margin, that was one of the few things Japan got right.
Robin is low tier.
Fox and Falco in the same tier.
Pac Man high tier. He would be Brawl top tier, but again victim of circumstance forces him to be low tier.
Duck Hunt Trio within an 18.5 mile radius of titans like Lucario, Yoshi, Greninja, G&W and
PIkaman Pikachu. Toxic characters are never good aka Brawl Sonic, unless they're broken aka Ice Climbers and Metagame Knight...
Extremely large high and low tiers. Please put in a middle tier.
Charizard and DK low tier, yet Bowser is high.
DayDayDay higher than the said two, even if by a small margin.
Samus < G&W, Pac, Jigglypuff, Bowser DDD, Jr, Caharizard, DK, Ganon, and Falco.
ROB high tier, even if near the bottom of it.
Fox lower then Mega Man.
Little Mac is bottom tier.
Metagame Knight doesn't have his own tier. Go away
tl;dr
