Black Adam is a muscular black-eyed powerhouse with short black hair slicked back. He also has pointed ears. He wears a skintight black uniform with yellow boots, a sash and a golden lightning bolt insignia on his chest.
After the captured heroes escaped, they contemplated liberating the villains, but decided not to and went to find their captor first.
Kylstar's Vessel December 1, 23:58UTC
The Justice League, Superboy, Miss Martian's valiant effort against Kylstar convinced him to treat his sentient weapons better. All captives, including Black Adam, were released, and Orb-One explained Kylstar's motives. He was a freedom fighter who was on a mission to stop slavers who destroyed his homeworld. As a sign of his good intentions, he offered to return captives unwilling to help with his fight back to their homeworlds. Those willing to stay were promised good treatment and glorious battle. Black Adam was intrigued with the offer, and decided to stay.
After the others have been teleported away, Kylstar explained to those who remained that the slavers were too powerful, and the best way to defeat them was to take over the galaxy first.
Super strength: When he attacked the Bio-Ship, waves of force emanated from where he hit, and he was also able to tear it open. When he was battling the young heroes, he was able to easily throw the Team around. He was capable of knocking out Superboy with a single hit. He later hit Kid Flash so hard he broke his arm.
In the comics, Black Adam is an anti-Captain Marvel (in fact, his predecessor). He draws his powers from the Egyptian pantheon of deities the same way Captain Marvel draws his from Greco-Roman deities and biblical characters.
This is his fourth animated appearance. He first appeared in Filmation's Kid Super Power Hour with Shazam!, then in Batman: The Brave and the Bold and Superman/Shazam!: The Return of Black Adam.
