File:X-Men Vol 1 19 001.jpg

Description
The X-Men are sent on a vacation by the professor for their hard work against the Sentinels and Magneto in the past few months. Bobby and Hank double date Zelda and her friend Vera Cantor, but they are confronted with a person named Calvin Rankin. He has the power to mimic people’s powers and skills. He learns about the secret identities of the X-Men. He later runs into Marvel Girl and by following her learns where the X-Men live. He pretends to want to join the team, but then fights them and kidnaps Jean to lure the team to an abandoned mine. There he intends to use their powers to recover a buried machine that was created by the Mimic's father and will make his abilities permanent, since the power currently only lasts for the duration when his target is near him. The X-Men manage to free Jean but are to late to stop the Mimic from operating his father's machine. Strange enough the machine didn't make his powers permanent, but instead it removes them entirely, as was the true intention of his father, who suspected that the abilities Calvin originally gained by a chemical accident would only cause him trouble.
