Which boss was the toughest for you? I say it's either the 2nd Battle with Riku (Hollow Bastion) or Sephiroth.
Well Sephiroth is an optional boss even though most find him the toughest. But some do think there is some tougher boss.AegisReflector said:When you list bosses, please list someone other than Sephiroth. >.<
The 2 Ursula battles were a pain in the ass since swimming in KH is incredibly awful.
