Blue Jay is a member of
Champions of Angor, alongside
Silver Sorceress and Wandjina. The three are respectively homages to Marvel Comics characters
Yellowjacket,
Scarlet Witch, and
Thor. After surviving the destruction of Angor, the three come to
Earth in an attempt to disarm its nuclear arsenal and save it from a similar fate. Wandjina seemingly sacrifices his life saving
Bialya from a nuclear meltdown. Blue Jay and the Sorceress are imprisoned by Russian officials. Both manage to escape, with Blue Jay joining the Justice League.
The Extremist Vector While with the League, they confront the
Extremists, robotic duplicates of the entities who had destroyed their world. The robots almost do the same to Earth, but are stopped by a combined effort of both teams. It is revealed that Mitch Wacky, a revered member of Blue Jay's world, had created the robotic Extremists but they had gotten out of control. Mitch ran a highly advanced theme park, where the robot Extremists were attractions. Mitch's technological resources had allowed him to survive the nuclear holocaust and he soon makes his way to Earth and a new life. Mitch's subsequent time travel adventure with
Kilowog would showcase Blue Jay's old friends and teammates, all analogues of
Marvel Comics superheroes. It turns out that
Dreamslayer, one of the Extremists, is not a robotic duplicate, but the real thing.
Leader for a mission Blue Jay becomes a member of the
Justice League under the command of liaison Catherine Cobert. During his tenure in
Justice League Europe, he spends most of his time wracked with self-doubt. He is one of the many to fall victim to
Starro, but
Ice stops its invasion. He is eventually made the leader of the
European branch of the League. He is assigned by Ambassador Rolf Heimlich, who had been placed in charge of the League by the people of the
United Nations. Blue Jay's first mission is to bring back
Blue Beetle,
Captain Atom, Ice, and
Elongated Man. They had all been fired by Heimlich and had teamed together to illegally invade Bialya to uncover the truth behind recent incidents. Inspector Camus discovers the truth behind Heimlich, that he is a mole sent by
Queen Bee, the ruler of Bialya. On the flight over, Blue Jay is given valuable leadership advice by
Martian Manhunter. The League uncovers Queen Bee's brainwashing plots in an explosion set by Sumaan Harjavti, who then kills the Queen. The explosion itself also almost kills the League but Ice saves the lives of every superhero and the brainwashing victims by forming an ice shield, but she is not able to save all of the local Bialyans, many of whom die. Blue Jay and the League stay long enough to participate in rescue and relief efforts.
Losing friends Dreamslayer eventually returns to take over the mind of Justice League financier
Maxwell Lord. Dreamslayer enhances Max's persuasion power and takes over the sentient island Kooey Kooey Kooey. Mitch Wacky is kidnapped to recreate the Extremists, but dies shortly afterward. During the Justice League raid on the island, the Sorceress is killed after being shot in the stomach by a brainwashed native.
Post-JLE activities Later, Blue Jay, as a reserve member of the Justice League, becomes involved in power struggles involving the
Rocket Reds and the villain
Sonar. He is kidnapped by acquisitive aliens, along with dozens of other superhumans. The stowaways,
Nightwing and
Firestorm, work to release
Superman. Their efforts free the hero, along with
Skyrocket,
Livewire, Veteran, and
Aquaman. Doubts about Superman's identity cause a schism in the team, but they work together to restore their powers, damage the facilities of their alien captors, and free everything that had been taken. This destroys the effort of an alien entity called the Auctioneer, who intended to sell off the entities of Earth for a profit. Due to a mistake by Livewire and the intentional transmissions of the aliens themselves, Blue Jay's efforts, along with the rest of his temporary allies, were broadcast to every television on Earth and to many alien worlds beyond. This makes them intergalactically famous.
Justice League of America Blue Jay later appears in the pages of
Justice League, where he is apparently killed by a mysterious unknown villain while attempting to warn the Justice League of a plot against them. He is later revealed to have survived and been captured by
Doctor Impossible, who plans to use him to resurrect
Darkseid. Impossible's efforts instead create a new villain called Omega Man. During the subsequent battle between the JLA and Omega Man, Blue Jay is freed by
Supergirl. Blue Jay leaves to explore the
multiverse, hoping to find a universe where he can become a true hero.
Heroes in Crisis During the
Heroes in Crisis storyline, Blue Jay is among the heroes attending the therapy center Sanctuary. He and many other Sanctuary patients are killed in a blast believed to have been caused by
Wally West. In
The Flash, it is revealed that all of the Sanctuary's attendees survived, with a group of clones having died in their place. ==Powers and abilities==
