Fantastic Four #33: Flamin' 'Eck
Script: Smilin' Stan Lee
Art: Jolly Jack Kirby
Inks: Chucklin' Chic Stone
Lettering: Amiable Art Simek
The conceit of this issue has the Fantastic Four battling to save Namor and Atlantis from invasion by Attuma, but without Namor ever knowing that he had assistance. To save time getting the team underwater, and to do so without giving them lots of breathing equipment, the creators come up with an aerosol spray that allows them to breathe underwater. But breathing is one thing - what about Johnny's flaming powers?
Thankfully, Reed's oxo-spray also resolves this. Thanks to the extra oxygen which has permeated his skin (and definitely not been used in any metabolistic reactions), Johnny can now flame on underwater (and extra-flame on out of water). As the title of this trope states, flamin' 'eck.
