Machine Head Hire[]

Battle Beast defeats the Guardians of the Globe, Invincible and Titan with very little difficulty.
Battle Beast was hired by Machine Head to help defend him from Invincible and the Guardians of the Globe, being promised that he would be given worthy adversaries to fight. In the ensuing battle, Battle Beast easily overwhelmed Invincible, Black Samson and Monster Girl. Disappointed by the strength of his adversaries and not being promised what he wanted, he promptly left and spared them, claiming that there was no honor in killing insects.

Battle Beast elsewhere..
He was later seen ambushing two guards on a ship somewhere in space.
Asteroid Prison Break[]
Imprisonment[]
Afterwards, Battle Beast's ruckus throughout space, somehow caught the attention of the Viltrum Empire, or a species that worked for them and somehow managed to capture him, sometime after two powerful enemies of the empire were incarnated.

Allen recruits Battle Beast!
Allen attempted to get as many inmates who were imprisoned to help him save Nolan but they were all gunned down by the guards, and Allen discovered his secret prison cell, opening the cage, and met the legendary Battle Beast. Battle Beast demanded who want give him the battle he so rightfully deserved?! Allen mentioned that he needed to help free his amigo, Nolan but the other viltrumites were his, upon hearing the viltrumites, Battle Beast was interesting and the two fought against hordes of Prison Alien Guards, Battle Beast was greatly ashamed and charged at Allen for his deceit, and decided to face Allen himself, that was until Allen noticed a rumble from a guard's blood, and realized Nolan was below and managed to find him.
Paradise Found[]

Battle Beast finds the perfect challenge.
Battle Beast was astonished by the viltrumites and was last met with the greatest challenge, while Allen was slightly bewildered by his response, admitting to them all that if his life was to expire, by the empire's warriors he would enjoy it all the more. He fought the guards, one of them, admitted that he will kill him for interfering, to which he coldly remarks: Is that a Promise? Then when the fight took into space, he fought and buried his hand into the chest of a viltrumite guard, who still fought back.
Following the end of the prison break, Battle Beast was last seen still fighting that same guard seeming wanting to have more out of him.
Later on, he brutally kills the same guard but he was frozen. When the unknown ship arrived, the guards picks him up. However, one guard checks that if Battle Beast was dead and until he wokes up.
