Physically I'd say his most attractive feature is his hair. Characteristically I'd say his most attractive/appealing feature as a villain is his intelligence though.
Hmm, probably his power and the amazing clothing he wears(especially in TP). That's what Ganon is attracts with me. I like that about him. Everything else is ok. His original theme song fits him really well with the clam attitude he always has when about to fight.
