Ulzak traveled to Earth after
Tlaango informed him that
Coven murdered fellow clan member and Tlaango's partner,
Caffrey, while an insane
Captain Marvel oversaw Coven's actions. Ulzak wanted to uphold his people's tradition of punishing all those involved, and upon arriving at his destination, began tracking any source of cosmic energy. This led him to Coven who had just stolen a massive amount of Marvel's power, and Ulzak gave Coven the chance to surrender peacefully. The punishment for murdering Caffrey would be banishment on a deserted world. However, when Coven refused to go with them, Ulzak ordered his troops to open fire, killing Coven instead.
