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.

Design
A Missile Diver is a humanoid Heartless with light blue skin covered in blue-grey and blue-white zig-zag patterns. It has four fingered-hands and flippers for feet. Its head is long and torpedo-shaped, even sporting a pale green propeller on its back tip. Its forehead is decorated by angular, black spirals and it has a fin on either side of its head. Its face is pitch-black with glowing yellow eyes and its Heartless emblem is on its chest.

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