meet Spider's Champion!! it's kinda a mix between Never Escaped's Soldier and Spider's Pet's Pet, where Chief was captured by Big Mama and brainwashed (Spider's Pet), but instead of brainwashed to be submissive he was brainwashed to fight (Never Escaped). This Chief, instead of being captured around 19 or 20 like in Spider's Pet, was instead captured at 16 and immediately turned into a fighter for the Battle Nexus. In this he's 26 years old, so that's 10 years of being mistreated and forced to fight in the Battle Nexus.

his default mood is "angry" because of his brainwashing, and he's extremely aggressive, but like Soldier he's very aware of what's going on around him even if he doesn't show it
