Wandjina is the name of several incarnations of a character that homage/parodied Thor from Marvel comics in the same way that Hyperion homages Superman. In his last incarnation he has two iterations: Thunderer and Wandjina himself, now called Wundajin.
Originally, Wandjina came from the planet Angor, in an other dimension. Along with Blue Jay and the Silver Sorceress they called themselves the Champions of Angor.They first encounter the League when aliens robots attacked their world and they went to the source of the attack, where they found the leaguers. After a brief misunderstanding, Leaguers and Champions leave as friends.
Post crisis, the original tale was altered: the Champions went searching help for stop the Extremists, but things don't went smoothly as they wished. When Wandjina and his friends returned, the world was a wasteland. Then these heroes came to Earth to try to warn the human race about the dangers of Nuclear weapons. Sadly they are tricked by Colonel Rumaan to fight the Justice League. Upon learning they are working for the wrong side Wandjina sacrifices himself to stop a nuclear reaction that would kill millions.
He survived but badly damaged and easily manipulable by the Byalban Queen Bee who controled him and used as a living weapon, until he was terminally stopped by Captain Atom.
On a flashback tale it was revealed how much Wandjina was member and leader of his team, who parodied heavily on the Marvel tropes as the nuclear accident origins, the soliloquies and the psycological traumas.
After 52, Angor, was reinvented as earth-8, where Wandjina still served as the Thor of his group,(this time, the Meta-Militia) but he had several differences with his previous incarnations: outside the cosmetical changes, he had a not-so-secret alter ego (Dr. Leonart Grant, colleague to Gorgon) and was a closet gay. He was killed by Gorgon. He was still a leader and a hero but now he was grittier and darker much like the the rest of Earth-8.
Wandjina reappears in Multiversity, but this time as member of the Retaliators and under the heroic name of Wundajin. He was beaten by his doppelganger, Thunderer of earth-7, a variation of earth-8.
Wandjina made an "unofficial" appearance in the last chapter of Avengers forever as an Avenger of an alternate timeline, in the middle of a battle royale between evil and heroic Avengers. He was punched by an one-eyed Hercules.
