When preparing it, Recoome says "Recoome... Ultra... Fighting..." as he forms a large amount of his energy around his body. He then shouts "...BOMBER!" and has the energy explode out of him in a massive blast, inflicting a large amount of damage and destroying everything within the attack's radius.
Recoome was about to use this attack in an attempt to defeat Goku on Namek. However, he is elbowed extremely hard in the stomach and defeated effortlessly by Goku before he can complete his Fighting Bomber, much to the shock of everyone present.
