Equiara

Equiara is the het ship between Equius Zahhak and Aradia Megido from the Homestuck fandom.

Canon
Equius has an obsessive crush on Aradia, and is quite possibly the only person still capable of weirding Aradia out in her ghost state. Equius was upset about how Aradia had become his superior (being his server player and thus in control of his physical environment), but then took perverse pleasure in being dominated by her, even ceding the leadership title to her.

Later, when Equius gives her a robot body (complete with artificial passion for him programmed onto an artificial heart that pumps indigo blood, an intentional choice to match his own caste) programmed to have romantic feelings for him, Aradia reacts very badly. She proceeds to flip the fuck out, rip her new heart out, beat it to a pulp, smack the shit out of Equius, and then surprisingly kiss him, seemingly not under the influence of her programming in any way. The exact nature of this relationship is unclear, though it seems they are wavering back and forth between the flushed and caliginous quadrants of troll romance, which is fairly common. Later, during the Ministrife, Aradia mentions that she never should have kissed [him]; at that time, it was such a mistake, most likely ending their difficult relationship for good and implying that she regrets it.

Fanon
Equiara is not a very well-received ship by the fandom. Most find Equius' casteist beliefs offputting, and his programming of Aradiabot to have feelings for him to be gross. They are rivaled by the more popular ships, Equinep and Arasol. In the 2010s, "Equiara hate anon", a person who was sending fans of the ship anonymous hate messages, became an infamous figure on Tumblr. Some may ship Equiara partially out of spite for this person.
