Collects New Mutants Special Edition, Uncanny X-Men Annual #9 And New Mutants (1983) #35-40. Mutantkind's best class takes a road trip via the Rainbow Bridge to Asgard and medieval magic madness, with evil god Loki to guide them to all the wrong places! Then, it's back to class under a new schoolmaster: the master of magnetism, Magneto! The ex-terrorist has turned teacher to atone for his crimes, but even if the New Mutants and the guest-starring X-Men trust him, the Avengers will be much tougher to convince! Featuring the Beyonder, Emma Frost and the Hellions!
