Cassandra "Cassie" Cage is the leader of Mortal Kombat X's new generation of heroes, acting as a direct fusion of her iconic parents, Johnny Cage and Sonya Blade. She is a literal 50/50 blend of her parents. She inherited Sonya's serious military training and tact, but balanced it with Johnny's Hollywood cockiness, pop-culture humor, and trash talk. Her fighting style is a mix of tactical military CQC and flashy martial arts. She relies on dual handguns, nightsticks, and shadow-boosted kicks. Her personality tends to be sarcastic and Pop-Culture Obsessed, but is naturally confident by being a strong leader of her team.

Jacqueline "Jacqui" Briggs is a core member of Earthrealm's new generation of defenders. She is the daughter of Special Forces veteran Major Jackson "Jax" Briggs and Vera Briggs. A former junior Olympic kickboxer, she enlisted in the U.S. Special Forces despite her father's trauma-driven objections to her joining military life. She fights with an aggressive, close-to-mid-range rushdown who relies on kickboxing fundamentals augmented by high-tech electronic gauntlets attached to her forearms. She is loyal and protective of her teammates, but tends to be pragmatic, and have a no nonsense mojo.

Kung Jin is a Shaolin archer, former thief, and core operative in Earthrealm's new generation combat unit. He is the younger cousin (and nephew figure) of the legendary Shaolin hero Kung Lao. Following Kung Lao's death Jin fell into poverty and crime, becoming an agile thief out of anger and cynicism toward the Shaolin order. ​His fighting style is versatile, long-reach that uses a multi-functional composite bow that acts as both a ranged weapon and a bo staff for high-speed martial arts strikes. Kung Jin tends to be defiant and guarded as he uses sarcasm, cynicism, and wit as armor. But he's also impulsively righteous, and ​Street-Smart & Pragmatic.
