As part of the All-New, All-Different Marvel event, the Black Knight arrives on Weirdworld after killing Carnivore while losing control to the Ebony Blade, which causes him to flee from the scene of Carnivore's death. Upon arriving on Weirdworld, he kills King Zaltin Tar to establish New Avalon and builds an army with the help of two warriors named Shield and Spear. Black Knight has the army built in anticipation of the arrival of the Avengers Unity Division, who are seeking to bring him to justice. After struggling to maintain his sanity, Whitman is forced to battle the Uncanny Avengers, led by the aged Steve Rogers, who wish to arrest him for killing a criminal when he was still part of the Avengers team. It is revealed that Whitman accidentally entered Weirdworld, along with a HYDRA submarine, from 1945. The members of Hydra on board the submarine became the group known as the Fangs of the Serpent to the inhabitants of Weirdworld. As the Uncanny Avengers arrive to arrest Whitman, he unites the armies of the land to fight against them. Eventually, he is defeated and a truce is made: Rogers will take the Ebony Blade back to Earth and Whitman will be free to rule New Avalon. However, Rogers is possessed by the Blade and attacks his teammates. Meanwhile, the son of the king that Whitman overthrew to become the new lord gathers the Fangs of the Serpent to attack Whitman. After their defeat, Rogers and Doctor Voodoo agree that the only person who can bear the toll of the Ebony Blade is Whitman, and the Blade also shows this by not allowing any harm to come to Whitman. As the Avengers leave, leaving behind an expert on the Black Knight who came with them to look after Whitman, it is concluded that Whitman had been maintaining his sanity better than everyone had thought. Whitman concludes that for now ruling New Avalon is good, and the story ends on a light tone, Whitman not being persecuted as he has suffered enough under the Blade's spell.
