Missile Diver

The Missile Diver (ミサイルダイバー) is an Emblem Heartless that is found in Kingdom Hearts Final Mix. They are unique due to this Heartless forming a symbiotic relationship with Jet Balloon Heartless, which summon them to rocket at the opponent. In appearance, the Missile Diver is a blue-colored form of the Screwdiver, which holds the same style of bond with Aquatanks. While in motion, Missile Divers have a red glow at their back end, like a rocket.

Strategy
While fast, these Heartless aren't that difficult to beat. Simply beat their Jet Balloon mothers and the rest comes easy.
