Eridan Ampora

Eridan is a member of the returning cast of twelve trolls from Homestuck itself, and is the second to appear after the main protagonist Sollux. Taking on the role of a secondary antagonist, the violet blood killed Terezi before the events of the comic, and is the reason why Sollux loses his two biitche2 after recording him talking about his cheating and forwarding the recording to Feferi. However, his attempts to break the heiress away from the gold blood end up in failure, when she almost immediately thereafter falls in love with the far superior Erilux Amptor. After this, though, he takes something of a back seat in the events of the comic, only having a notable role in the Sollux x Vriska timeline thus far, in which he rallies his fellow incels to steal Feferi's airship bomb his arch rival's hivestem. Though he did give pursuit to Sollux afterwards, who had been rescued by Kramer piloting a ship of their own, he quickly abandoned chase when the grape blood told him that if he kept chasing them, he'd be supporting equal rights for women. Eridan has not been seen since, having presumably returned to his hive.

Trivia

 * Despite the fact that he is said to be an incel, and appears to be strongly against women's rights, Eridan is seen on Feferi's ship working with several female sea dwellers alongside his fellows. The reason for this is not known, although it could be speculated that it was a temporary alliance between regular incels and "femcels."
