Cull Obsidian Synergy Guide
Cull Obsidian is a Cosmic class champion in the Contest of Champions who forms a synergy with 15 other characters, available as a 3-Star, 4-Star and 5-Star champion.
A ferocious combatant like few others, Cull Obsidian is always seeking a truly challenging fight to impress his master, Thanos. Wielding his one-of-a-kind multi-weapon, Cull tears his opponent's defences apart and stops heroes in their tracks. Lord Thanos won't be stopped so long as his imposing enforcer, Cull, stands by his side ready to strike down any opposition.
