Editing Cyclops (Marvel Comics) (section)

=== Extermination ===
The entire X-Men team find themselves hunted on two fronts with one group being the mutant-hunter known as Ahab from a dark possible future where he has turned various mutants into his 'hounds' to hunt their fellows, and another being a younger version of Cable,<ref>''Extermination'' #1</ref> who is so determined to send the young X-Men back to their own time that he actually kills his own future self to stop him interfering, as well as performing 'surgery' to restore Warren's original feathered wings. After Mimic is killed when he acts as a decoy to save young Cyclops,<ref>''Extermination'' #4</ref> the original five accept the need to return home, but only after taking a detour into the future to meet the younger versions of Ahab's key mutant soldiers, allowing Jean to learn how their powers work. With this new knowledge, Jean is able to program a 'time delay' on the original five's memories once they return to the past, erasing all knowledge of events in the future until they reach that point, simultaneously granting the present Jean with knowledge of how to stop the Hounds. The timeline is thus restored to its original course, with Jean, Hank, Warren and Bobby meeting for milkshakes to talk about their new memories, unaware that young-Cable is talking with a now-alive adult Cyclops.<ref>''Extermination'' #5</ref>
