How to unlock the Supreme Arbiter achievement in Killer Instinct - Definitive Guide
A Supreme Victory is when you defeat an opponent without losing one of your 2 life bars, so, essentially by not losing a round. This must be done in an online match and is best done when going for "Friendly Arbiter".
