i think that ganon has a small chance at doing well in a tourney.
until someone finds some groundbreaking technique with him, he'll probably stay like that and just be low tier. but i must say that many people don't look at ganon's strengths... only his weaknesses. and a lot of complains are stupid...
"He's fat!"... really?
"He runs gay"...does that even matter?
I think he has potential, just minimal. More people need to start using him so that there will be more Ganondorfs ranking in tourneys and a higher chance of a new technique to be found.
Still, he's my favorite character and so I'm gonna stick with him until the end!
