This is by far Vaughan best work with X-Men so far.

This time we have Magneto still in jail but some are planning to break out...his cell mate. It happens to be another mutant who lost control of her power and killed people. So now she's stuck inside with Magneto since they share the same power. So a band of mutants including Havok decide to break her out. But they'll have to go through the X-Men AND the Ultimates.

This is pretty fun and a real stringer in the ending. It also shows a more calculated Magneto which was nice. I also liked the relationships here and how the characters all interacted. This also built some good future storylines like Peter and Kurt and Bobby and Kitty. Overall, this is one of the stronger volumes of the Ultimate X-Men universe and Vaughan best.

A 4 out of 5.
