Exodus then appeared to the mutants of Genosha, telling them to kill all humans or the entire island would be crushed under his force field. The Avengers and X-Men teamed up and took the fight to Exodus, but it proved futile. It was not until Professor Xavier unleashed a powerful psionic attack on Exodus that Black Knight was able to sneak up on Exodus, cutting through him with his energy blade. Exodus, weakened and defeated, left for Avalon, but not before unleashing a powerful attack on Quicksilver. It was also revealed during this battle that Black Knight remembered Exodus, but not from where or when.
