Professor X detects a new mutant and sends the X-Men to investigate. They arrive at a carnival and encounter the Blob, a very fat sideshow attraction who can bounce bullets off of his malleable hide as well as anchor himself to the earth and become immovable. The X-Men bring him back to the mansion as a potential member but the Blob spurns their invitation and returns to the carnival. Realizing that the Blob knows their secret, the X-Men lure him back to the mansion where Xavier wipes his memory.; The Thing and the F.F. hire Matt to look over the new lease on the Baxter Building. Matt goes to inspect the property but, unbeknownst to him, Electro has broken in to steal all of Reed Richard's secrets. Mayhem ensues.
