Sentinel Synergy Guide
Sentinel is a Tech class villain champion in the Contest of Champions who forms a synergy with 19 other characters, available as a 3-Star, 4-Star, 5-Star and 6-Star champion.
Although the Sentinels were created by a Mutant elite, who had the goal of controlling the Champions of The Contest, 100 years in the future, they rebelled; killed their creator and subsequently engineered a way into the present day. The Mark-ISO evolved from these rogue Sentinels, adapting to the ISO-8 rich environment of the current Contest. Powered by an ISO fusion engine, the Mark-ISO Sentinel can quell any uprising within The Contest with extreme prejudice.
