no way at all he is stronger than all 3 combined into kefka at allThen he's not beating Ganon.
"almost laid the world into ruin" which you kept repeating, ganondorf didn't even do that on his own he just revived/released monsters, he just sat in a castle and did nothing all day. Hell the Gods from FF6 wasn't even attempting to destroy the planet it was just happening in the conflict which they saw was wrong of themGanon didn't want to end the world either, just to rule it. Otherwise he would have pulled a Majora and brought down the moon.
Kefka destroyed most of the planet,I disagree, and Ganon didn't want to.
re-arranged it, created new monsters and magic,Ganon's done it.
Just the death of Kefka ended all magic, he was magic itself.Moot.
In terms of raw power, even the three goddesses could not seal Ganon away, even with the master sword pinning down his power, in WW.
