Screwdiver

Screwdivers are enemies from Kingdom Hearts and Kingdom Hearts: Chain of Memories. They appear in Atlantica in groups and are often accompanied by an Aquatank. They are stealthy heartless that use their propeller for thrust and strike with their edition of the triton. They have a variation in Neverland called the Missilediver (only in Kingdom Hearts: Final Mix).

Kingdom Hearts
''Heartless that acts with Aquatank. Unpredictable creatures, dashing forward one minute, cowardly retreating the next. They are invigorated by the sparks from Aquatank.''

Kingdom Hearts: Chain of Memories
A Heartless that likes to team up with the Aquatank.

It attacks with a spear or charges its enemies.
