S.H.I.E.L.D.

S.H.I.E.L.D. is an organization appearing in Never-ending story.

Never-ending story
At one point, S.H.I.E.L.D acquired a helicarrier. The Batcave, which was turned into a rocket, headed straight to the helicarrier when The Avengers, The Guardians of the Galaxy, SpongeBob SquarePants and Gary the Snail were teaming up to stop The Joker and Harley Quinn.

SpongeBob was able to stop Doctor Doom, his Doom Bots and Mrs. Krabs from making Patrick Star and The Justice League crash into the helicarrier.

S.H.I.E.L.D., along with all characters from Marvel, was sucked into a portal. However, some popcorn (that was being eaten by Patrick Star, Gary the Snail, Squidward Tentacles, Sandy Cheeks, Eugene Krabs and Plankton) turned into a plot hole, and the Marvel characters came out of it. Uncle Grandpa and Steven Universe fixed the plot hole.
