We return to the Silver Age with X-Men issues 13 through 18. We also provide a history of 1966's "The Marvel Super Heroes," which is the first cartoon based on Marvel's super heroes (obviously). And it also marks the first animated appearance of the X-Men...who aren't called the X-Men because of rights issues.
