ZelImpa

ZelImpa is the femslash ship between Impa and Zelda from The Legend of Zelda fandom.

The Legend of Zelda
Ganon attacks Hyrule Castle and demands the Triforce of Wisdom. Before being kidnapped, Princess Zelda commands Impa to flee and find the one who can save Hyrule. Impa agrees and flees in search of a hero. She later finds Link who saves her from some of Ganon's minions. Afterwards, Impa realizes that Link is the destined hero and asks him to go save the princess.

Adventures of Link
Years after the defeat of Ganon, the mark of the Triforce of Courage appears on Link's hand so he goes to ask Impa about it. When she sees the mark, Impa remembers the story of the original Princess Zelda that was passed down through her family and tells Link about it. She then shows Link to the sleeping princess and tasks him with traveling to the palaces so that he can wake her up.

Ocarina of Time
Impa serves as Zelda's personal attendant. When the princess has a premonition of Ganondorf attempting to take over Hyrule, Impa is the only one to believe her along with Link. The hero later arrives and Zelda tasks Impa with teaching him her lullaby and showing him to Death Mountain. Eventually, Ganondorf pursues Zelda so Impa flees with her on a white horse. They go into hiding for a while and taught her about disguising herself as a Sheikah named Sheik.

Once Zelda was able to take care of herself, Impa returns to Kakariko Village and heads to the Shadow Temple when an evil escapes. Link manages to save Impa and she awakens as the shadow sage. She assures Link that Zelda is still alive and they would be reunited soon and she would explain everything. Zelda is later kidnapped by Ganondorf so Impa helps Link reach them. After Link manages to defeat Ganon, Zelda calls upon the power of the sages and Impa helps seal him away.

Oracle of Ages and Oracle of Seasons
Princess Zelda senses that the oracles Din and Nayru are in danger and sends Impa to go and retrieve them. Unfortunately, both end up being captured so Impa is forced to have Link save them. While Link is saving the second oracle, Koume and Kotake capture Princess Zelda. Impa informs Link of this and has him save her after both oracles are saved.

A Link Between Worlds
Impa is once again serving as the nursemaid of Princess Zelda. After Yuga turns the sage Seres into a painting, Link requests an audience with Princess Zelda and Impa escorts around the castle. At some point, Yuga comes to Hyrule Castle and turns Impa into a painting before doing the same to Zelda. Link later travels to Lorule and after saving Impa and all of the sages, she helps Link obtain the Triforce of Courage so that he can go save Zelda.

Hyrule Warriors: Age of Calamity
Impa serves as the Royal Advisor of Hyrule and "loyal friend" to Princess Zelda. She appears to care deeply for Zelda and is constantly worried about her well-being. The two appear to be close, with Zelda trusting and confiding in Impa about her insecurities often.

When Courage Fails

 * The mission opens with a cutscene of Princess Zelda praying at the Spring of Courage, expressing her self-doubt and insecurities about not being able to "live up to her own potential." Impa, standing nearby, looks very worried for Zelda, sadly saying her name before trailing off. She then attempts to distract Zelda, suggesting they go "take a break somewhere" and awkwardly exclaims how hungry she has become. Zelda seems touched by this, saying "Impa..." softly before looking back at the spring sadly, stating that there's "no more time."
 * Throughout the actual gameplay, Impa is constantly worrying about Zelda's safety and well-being.
 * Impa: "Princess, I appreciate your valor, but if things get bad, save yourself. Can you promise me that?" —After defeating the monsters trying to enter the Spring of Courage.
 * Impa: "Princess! Are you well?"                                                                                                                                                                                                                Zelda: "Yes, I'm fine."                                                                                                                                                                                                                                         Impa: "What a relief! Now, please don't fret. We'll make quick work of those foul monsters." —After going to aid Zelda.
 * Impa: "Princess! You look exhausted. Won't you please... No, I insist. Take a rest at once." —After Zelda collapses.
 * After the mission, Princess Zelda hurriedly asks if Impa and Link are alright, concerned. Impa smiles and says that they are alright because of Zelda, that she saved them with her "keen senses."
 * Zelda begins to doubt herself and her abilities once more, which causes Impa to say "Now you listen to me!" while getting very close to Zelda's face. Zelda appears to be taken aback and flustered by this action. Impa then, quite vehemently, challenges her self-doubt and declares how Zelda's actions saved their lives, saying that her efforts are valued and are "not in vain." Zelda gently thanks her and the two share a smile.

Fanon
ZelImpa has a small amount of popularity in the Zelda fandom. Depending on the game, many find this pairing to be slightly gross due to the fact that Impa is elderly. However, there are some games where Impa is younger. Ocarina of Time is the first game to show a young Impa. The two are seen riding a horse together and Impa is shown to look after Zelda for a while. Skyward Sword also shows a younger Impa in the past who is also loyal to Princess Zelda. There have also been fans who see Impa being a mother-like figure to Zelda, since many of the games have Zelda losing hers at a young age while Impa caring for Zelda in whatever way she can has the Sheikah filling a void in Zelda's life. Age of Calamity shows the two to be quite similar in age, with Impa being around a year or so older than Zelda, and taking on a more "supportive friend" role as opposed to a mother-like role, which many consider to be filled by Urbosa.

Trivia

 * Like in Ocarina of Time, Zelda disguises herself as the Sheikah Sheik when she disappears in the storyline of Hyrule Warriors, only this time Impa had no idea that Sheik is her missing princess is disguise and was shocked by Sheik's clam of "him" being a member of the Sheikah Tribe, her tribe. This has Impa questioning whether or not she should trust Sheik, while Wizzro took advantage of the princess's absence to disguise himself as Zelda. When Impa learns that "Zelda" had bewitched the Gorons into kidnapping the princess of the Zoras, she refused to believe it and made it her mission to confront the fake Zelda, with Sheik assisting her. After they defeated Wizzro as "Zelda" before "unmasking" him, Sheik reveals "himself" as the true Princess Zelda; Impa is pleased by this and that Zelda is alive, and had been with them all this time. Zelda apologies for keeping her true identity a secret from Impa and the others.
