Hook Bat

Hook Bat is a Heartless that appeared in Kingdom Hearts II, it resembles a bat, and is capable of ambushing at unexpected times. It can be difficult and annoying to hit, since it mostly evades your strikes by simply flying. Using the reaction command allows Sora to grapple the hook on Hook Bat and swing wildly, damaging all foes in range. An alternate tactic is to cast Magnet to attract it and finish it with a strong spell.

A more powerful version of this Heartless called Perplex can be found in the Cavern of Remembrance
