4. KISS (Howard the Duck)
Roughly halfway into Howard the Duck’s 27-issue run, Howard becomes tormented by nightmares and journeys to Cleveland in an apparent attempt to rid himself of the bad dreams. While on the bus, he meets Winda Wester, a girl who’s being sent by her parents to get an unnecessary exorcism in Cleveland. They soon become friends but things take a turn for the worst when Howard’s enemy The Kidney Lady steps onto the bus and starts causing trouble. After a fight breaks out that causes the bus to crash both Howard and Winda get sent to jail.
After hearing their story, the prison doctor agrees to perform the exorcism on Winda himself. To everyone’s shock, Winda’s thoughts manifest themselves physically during the exorcism and they take on the form of American rock band KISS. It’s later revealed that Winda has latent psychic abilities which include the ability to project illusions.
Though the cameo was certainly a strange one it actually led to the KISS getting their very own comic book series.

3. Uri Geller (Daredevil)
For anyone not familiar with Uri Geller, he became super famous in the 1960s and 70s when he claimed to have telekinetic powers. Despite being exposed as a fraud by Johnny Carson on live TV in 1973, to this day he still claims that he can use his mind to bend metal objects.
Being a big fan of magic, Stan Lee decided that he had to have Geller somehow incorporated into the Marvel Universe and called on writer Marv Wolfman to figure out the best title to put him in. The result was Daredevil #133, where The Man Without Fear finds himself in need of Geller’s special abilities after the villain Mind-Wave sends an army of psychic beings to attack New York.
When Geller meets Daredevil, he reveals his fantastic origin story which involves being abducted by aliens as a child and imbued with the amazing power to bend the living hell out of kitchen utensils.
Once the battle starts, Gellar proves just how useful he can be by bending a metal pipe that one of the psychic goons was going to use to bash Daredevil with. Of course, a bent pipe is still perfectly suitable as a weapon, but Daredevil was a good sport about it and thanked Uri for his contribution anyways.
