Assistance Bombers are assumed to be allies to White and Black Bomber who have been trapped by the enemy. In the introductory cinematics of Super Bomberman 4, some of them are shown falling out of the Bomber Shuttle into the black hole and being sent through time. In Neo Bomberman, they are seen participating in a tournament when Professor Bagura begins his attack, and are presumably captured during the ensuing events.
Each Assistance Bomber seems to share the same AI pattern. They operate with low intelligence, moving slowly and placing few bombs to destroy soft blocks or enemy characters. However, they are invulnerable to both bomb blasts and enemies, cannot be thrown or pushed, and cannot pick up power-ups, so their existence is generally not detrimental to the player(s). Assistance Bombers remain on screen until the stage is completed.
