Tavrisprite

Tavrisprite was Jane Crocker's sprite after being prototyped with Vriska Serket's and Tavros Nitram's corpses, by Gamzee Makara. They seem to have trouble reconciling their two drastically different personalities into a coherent new one. Their horn configuration resembles Tavros's large ones, but with Vriska's pincer and stinger tips. They also have Vision Eightfold and mascara, but the shape of their eyes are Tavros's. They wear a short-sleeved button-down shirt over a t-shirt, similar to both Vriska's and Tavros's outfits, with a new symbol on it, a mix between the Light symbol and the zodiac sign for Taurus. The rest of their body is the ghostly tail possessed by all sprites. The sprite's color and text color match John's text color, as Nannasprite's color and text matches Jane's text.

Tavros and Vriska's dead selves later reappeared in a dreambubble and began their quest to find the weapon that can defeat Lord English.

Personality
Tavrisprite immediately expressed their extreme psychological agony and hatred for aspects of themselves (and everything else). After finding their merged personality so completely irreconcilable, they had the fortune to mercifully "Tavrispl♉de!" effectively ending their short existence.

Speculation
Tavrisprite has something of a parallel to Jadesprite, since their predecessors were dead for a long period of time before being prototyped. They also possess intense self-conflict. The extent to which, like Jadesprite, one prototyping may have overridden the other has yet to be seen.

Similar to the way Jadesprite retained First Guardian powers, it can be safely assumed that Tavrisprite had retained some of Tavros' and Vriska's abilities (stealing luck and possibly The Windy Thing, as well as their troll powers of mind control and the ability to commune with animals). However, since this is a post-entry prototyping, such abilities gained were not transferred to the Alpha Session's underlings.

It can be surmised that Tavrisprite is a jab at the massive fandom speculation of various potential resurrections via prototypings, as well as the concept of shipping the two in general, in particular, the act of combining two names into one as something quite common to shipping couples (TAVRoS + VRISka).

Trivia

 * It is the only Alpha sprite so far in which both trolls' horn styles are combined into one.
 * It's interesting to note that it is not Vriska's zodiac symbol but her aspect symbol that is represented in Tavrisprite, unlike the other Alpha sprites. This is most likely due to the fact that Vriska was in her god tiered form upon death.
 * It's the only Alpha sprite to explode.
