Monster Association Arc
He was sent by the Monster Association, together with Royal Ripper and The Bug God, for the purpose of saving Garou from the incursion perpetrated against him by Bang and Bomb (and also Genos that was fighting him at the scene). After Garou was appointed from the Association to kill 100 humans to prove his monsterish nature, The Bug God, Royal Ripper and Senior Centiped followed the human monster to watch over his actions; when they discovered that Garou didn't wanted to abandon his humanity and was also defending a little kid, Busaiku, they attacked him and tried to kill the child. After an hard battle, Senior Centipede was killed and The Bug God and Royal Ripper defeated Garou, but moments before they could finish him they were recalled by Psycos to the base because of the attack to the Monster Association from the Heroes Association. Also, Royal Ripper brought Busaiku back to the Monster Association headquarter to vent his blood lust on him, instead of killing some random allied. During the attack to the Monster Association, since he couldn't wait no longer, Royal Ripper began his torture on the poor kid, but before he could lay a finger on him, Garou entered the scene, determined to save Busaiku, and after taking some damage from Royal Ripper's attacks, he beheaded the cruel monster.
