BEWARE Of The BLOB!
1st Appearance of "BLOB" (Frederick J. Dukes)
Professor Xavier interrupts the X-Men's latest training session to inform them that he has mentally detected a new mutant nearby. The X-Men find the mutant known as the Blob working at a carnival. They invite the Blob into the school so that Professor Xavier can test his powers. Afterwards Professor Xavier invites the Blob to join the X-Men, but he refuses. In an attempt to maintain the X-Men's secret identities, Professor Xavier tries to mind-wipe the Blob, but he is able to escape.
Later the Blob returns with the other carnival people and begin to attack the school. The X-Men are able to hold off the carnival people long enough for Professor Xavier to use a thought intensifier to erase the carnival people's memories.
