Dive Mech (サプライズ, Surprise, in Japan) is an enemy that appears in Bomberman 64. It is designed to repel intruders from the Black Fortress. It flies high above the ground, thus evading both Bomberman and explosions, and constantly pursues Bomberman. If Bomberman comes too close, Dive Mech will dive down toward him with its sharp wings extended. This attack will harm Bomberman and detonate bombs on collision.
Because it is a robot, Dive Mechs cannot be stunned by kicked or thrown bombs. It takes one bomb blast to destroy, but it is normally too difficult to hit it with anything other than a mid-air Pumped Bomb explosion. In Hard Mode, it moves and dives more quickly, and takes two bomb blasts to destroy.
