Klonnie

Klonnie is the het ship between Bonnie Bennett and Klaus Mikaelson from the The Vampire Diaries fandom.

Canon
The two first "met" when Bonnie had planned to kill Klaus using the power of a hundred witches behind her back. Klaus, while posing as Alaric discovers this, and mentions it to his sidekick, Maddox who is a warlock. Maddox informs him that it would kill any witch to use that much power, and all Klaus would need is to provoke her enough for her to die. Klaus realizes he needs to get rid of Bonnie before he can get his hands on Elena, and he poses as Alaric at the Mystic Falls High School dance. Klaus corners Elena and Bonnie, and Bonnie does her best to take him down, using all of her powers. Bonnie falls to the floor dead. It is later revealed that Damon and Bonnie had secretly collaborated and decided to put a protective spell on Bonnie, so that it would appear as if she was dead. This led Klaus to believe that he had taken down Bonnie, unaware that she would later appear as a secret weapon to take him down.

In The Sun Also Rises, Klaus becomes vulnerable after unlocking the Werewolf part of himself, and this gave Bonnie a chance to weaken him enough for Elijah to finish him off. Unfortunately, in order to see his family, Elijah betrays Elena and Bonnie and saves Klaus from death.

Bonnie and Klaus properly meet in The Reckoning where Elena yells at Bonnie to run before she is encountered by Klaus. He says to her "I was wondering when you'd show up." Klaus explains that every time he tries to turn a werewolf into a hybrid, they die during transition (because of Bonnie's interference), and forces her to use her powers to let his hybrid plan work by killing Tyler.

Fanon
Klonnie is one of both Bonnie and Klaus' most popular rare-pair ships. Many fans think a relationship between the characters should've been explored in the show, and prefer to ship it over Bonenzo. Some fans like to ship it alongside Klaroline and Bamon because of the chemistry between Joseph Morgan and Kat Graham. It is Klaus' most popular rare-pair ship and Bonnie's second most popular.
