The early days of mutant fun returns! Unfortunately, the X-Men are a male-dominated group in this early time. Concerned that star pupil Marvel Girl could use a role model, Professor Xavier enlists the world's top female hero - Sue Storm, The Invisible Girl!

Her team mates realize how much they miss her when Sue takes Marvel Girl off to join the Fantastic Four - but is the young mutant ready to face the likes of The Mad Thinker?
