JLX (1996)

Mister X assembled Apollo, Firebird, Nightcreeper, Mercury, Wraith, and Runaway. Together the team became known as JLX, and freed the Mariner from where the JLA had locked him away. The Mariner joined the team. After the JLX had freed the Mariner, the JLA went after them. In an epic battle shown in JLX #1, the entire JLA fought against the JLX. The battle stopped after Mister X contacted Angelhawk, informing him to fake an injury, which he did. In turn, Mister X kept Angelhawk's metamutant origins a secret.
