Fantastic Four #28 (1964)

In Fantastic Four #28, the Fantastic Four are discussing the X-Men. Meanwhile, the Puppet Master and Mad Thinker are cooking up a plan to stop the Fantastic Four. The Thinker orders the Puppet Master to create a puppet of the X-Men's leader, and manages to create a puppet of Professor X. This puppet can control him, and Professor X then tells the X-Men to capture the Fantastic Four. The X-Men obey him and make their way to the Baxter Building. When they arrive and greet the Fantastic Four, Professor X mentally commands them to capture the team. A battle ensues, and it's a stalemate until the X-Men capture Sue Storm and take her to an island. Once there, various traps are set for the Fantastic Four, including a massive pit for the Thing to fall into. The Mad Thinker and Puppet Master arrive, ready to command Professor X to subdue the X-Men, but Beast manages to smash the puppet of Professor X just before succumbing to the command. Meanwhile, the Thing digs handholds in the wall to escape from the pit and frees the other members of the Fantastic Four. Together, they and the X-Men fight the Mad Thinker's android, but can't do anything to it. Professor X uses his mental powers to shut the android down and save the group from destruction. The Mad Thinker and Puppet Master escape, and the X-Men apologize to the Fantastic Four for fighting with them.
