The third episode of Mr. Mech, Once a Mech, Always a Mech, focuses entirely on Mr. Mech's judgment of Tyrontics and Krixool. Mr. Mech states that there can be no emotional attachments between gladiators of the Mech Arena and orders Tyrontics to kill Krixool. Faced with certain death, Tyrontics struggles with this decision, but Krixool instead places himself at Mr. Mech's knees and offers to be his sex slave. In spite of Tyrontics' objections, Mr. Mech accepts his Krixool's offer and has Tyrontics taken away and imprisoned.
