Its not completely about how he would of fit but that the design could still be used, maybe not for skyward sword or twilight primces but could be used for another Zelda game.How? They later changed Ganondorf's design in TP. It was art for TP and TP only. I don't see how "forgetting about it" has anything to do with this. Especially since Ganny wouldn't have fit in SS.
I love it! Great idea dude!That concept art doesn't really fit for me as a suitable boss to replace Demise in Skyward Sword or bosses for the matter. It works better in a Zelda game where Ganondorf was old and dying, perhaps drained of his power and he intends to find a way to make himself young again much like the Joker from Arkham City. If I have to change the boss design for Demise, I'll give him some kind of battle armor that resembles Demise in the cave paintings, with three horns sticking out and shrouded in shadows.
You and that Ghirahim, oh boy.I like Ghirahim for boss. Ganon's a good idea but not the best.
