Kakinbatank (カキンバタンク Kakinbatanku) is an enemy encountered in the first Wily stage in Mega Man 9. It is a large robot on treads and initially holding a shield. In their default state, Kakinbatanks are docile, doing nothing, while their eyes are closed. When disturbed, however, a Kakinbatank will attempt to crush the player with its shield, shoving it forwards when Mega Man is close by. After it shoves its shield forward, the Kakinbatank starts shooting red projectiles from its mouth. Since it is a large-sized enemy, it is resistant to Black Hole Bomb and Tornado Blow. However, Laser Trident can pass through its shield. Kakinbatank has red and green variants, both of them appearing in the first Wily stage. The red variant also appears in Fake Man's stage.
Etymology
Its name is probably a combination of the words, "kakin (カキン)", "batan (バタン)", and tank. The first is Japanese onomatopoeia of reflect sound. The second is Japanese onomatopoeia of fall down sound.
