Mercury and the rest of Cerebro's X-Men disrupt the voyage and kidnap Shadowcat to eventually meet with the alive form of Cerebro, impersonating Professor X. It is then revealed to Shadowcat that Cerebro's X-Men have also kidnapped Dr. Peter Corbeau. Dr. Corbeau knew about, and had plans to destroy the Benassi Rocket, a military rocket set to track down and destroy mutantkind. Cerebro, with the aid of Cerebro's X-Men wanted to prevent Dr. Corbeau from reaching the X-Men, so that he can take care of it on his own. Eventually the X-Men have succeeded in defeating Cerebro's X-Men and ruin Cerebro's plans.
