Combined Bombermen are Bombermen that have been created by the "Combined Bomberman Making Machine." They appear in the anime, Bomberman Jetters. They were most often created with whatever is available nearby, usually being animals.
The machine was created by MechaDoc at the end of episode 2. The machine resembles an ostrich and has a chair attached beneath it for the user to target an object. The beam is fired at the target and turns whatever it hits into a Bomberman, giving it the ability to throw bombs and an antenna atop its head.
