Acuba (突撃水兵 アクバ一 Totsugeki Suihei Akuba Ichi?, lit. "Assault Frogman Acuba") is an enemy in the Contra series.


A scuba diver sharpshooter soldier who has been brainwashed by Red Falcon's forces. A couple of them are encountered while ascending the Waterfall stage in Contra.

They can initially be seen crouching inside the cascade's streams, although they cannot be harmed while in this state; they can only be killed as they are peeking out of the water to attack, which only happens after the player is at a higher level. At this moment, they will emerge and quickly shoot a projectile straight up; once it reaches a certain height, it will explode and divide into three shrapnels which will then rain down, effectively covering a considerable area.

They are not to be confused with Guerrilla Soldiers, another enemy in that same game that also emerges from the water.

In Operation C, they shoot normal projectiles at the player instead.
