Kummi

Kummi is the het ship between Kuruk and Ummi from the Avatar: The Last Airbender fandom.

Canon
Avatar Kuruk never had the intention of settling down before he met Ummi from the Southern Water Tribe. He was seen as a carefree and arrogant avatar who traveled around the world challenging people to fights and showing off. Kuruk slept with multiple women and earned his reputation as a heart-breaker, as very few knew that he was depressed as a side effect of defeating dark spirits and trying to 'feel something' in order to compensate for the damage. All of that changed at the New Moon Celebration when Kuruk met Ummi.

Kuruk and Ummi met at the New Moon Celebration. Kuruk was the current avatar from the Northern Water Tribe and had no desire to settle down as he preferred to bask in his fame. However, he met a girl named Ummi from the Southern Water Tribe at the New Moon Celebration when the tribes would come together. Kuruk described it as being love at first sight. The two spent a lot of time together and soon got engaged. Kuruk and Ummi had their wedding at the Spirit Oasis but before the ceremony was complete, Koh the Face Stealer snatched Ummi and took her away as punishment for Kuruk's previous arrogance.

Kuruk spent the rest of his life and even afterlife trying to save Ummi from Koh who had stolen her face. He would travel to the Spirit World on the anniversary of their wedding every year in an attempt to save Ummi from Koh but always failed. Kuruk passed away a few years later at the age of 33 due to the illness that the dark spirits caused him. When Aang visited the Spirit World centuries later, Kuruk was in the Realm of Koh, still searching for him in an attempt to rescue Ummi.

Fanon
Kummi is a rather popular Avatar ship. Many fans like Kummi as a tragic ship. A lot of fanfiction writers have written stories about future avatars connecting to Kuruk and finally saving Ummi from Koh so that the two can finally rest in peace. Shippers of Taang have theorized that Ummi was eventually reincarnated as Toph and was born blind because she had her face stolen in a previous life. Because of this, Kummi is especially popular among the Taang shippers.

Kummi was largely unopposed as a pairing for Kuruk prior to the release of the Kyoshi novels. With the introduction of Hei-Ran and the Heiruk pairing, Kummi gained a rival ship. Some fans felt that Kuruk had more chemistry with Hei-Ran and believed that she was a more important part of his life than Ummi was. Kummi fans, on the other hand, point out that Kuruk ruined his chances with Hei-Ran and that Rangi would have not been born if Heiruk happened. However, some fans of Heiruk and Kummi are still able to appreciate the other ship or even multi-ship Heiruk and Kummi.
