ZelPit

ZelPit is the het ship between Pit and Zelda from the Super Smash Bros fandom.

Super Smash Bros. Brawl
In the Subspace Emissary, Pit and Zelda are both major characters in the story, but their paths do not cross.

Super Smash Bros. for Wii U and 3DS
Should Pit activate Palutena's Guidance in a battle against Zelda, Palutena will comment that it's not quite the Zelda Pit is used to. Pit is already aware that Zelda had lost her shapeshifting ability she had in the previous game. When Palutena tells Pit about Zelda's new special move "The Phantom Slash", Pit asks where she gets the Phantom from. Palutena guesses that she uses magic, which causes Pit to be amazed at her being such a powerful magician. After Palutena teases the idea of giving Pit his own Phantom, Pit freaks out for a bit, causing Viridi to barge in and laugh at Pit's misery, but also giving him advice on how he can knock Zelda's Phantom out.

However, despite knowing that Zelda can shapeshift, neither Pit or Palutena seem to have any clue about Sheik's true identity, which Viridi calls them out on.

Super Smash Bros. Ultimate
In the "World of Light" cinematic opening, Pit and Zelda are shown to be commanding an army of united fighters. They both get promptly consumed by Galeem, but also have the option to save each other if the player chooses to play as one of them while fighting to free the other.

In this version of Palutena's Guidance, Pit is completely awestruck about meeting Princess Zelda. After Palutena gives a round-up about what version of Zelda this is, Viridi pretends to be Zelda using telepathy on him and asking him to give her a cinnamon roll. Pit actually falls for it at first, and has a rather smitten tone when accepting "Zelda's" request, only to get annoyed when he realizes that it's Viridi. Palutena tells him to focus and be careful about Din's Fire. Viridi then pranks Pit again by telling him to get "Zelda" a glazed donut, which Pit once again falls for.
