Erisolsprite

Erisolsprite is Jake English's sprite after being prototyped with Eridan Ampora's and Sollux Captor's corpses under unknown circumstances, presumably involving Gamzee Makara since he is seen taking Sollux's corpse and seen with Eridan's head during his killing spree.

Trivia

 * In [S] Act 6 Act 5, his tail, when drawn in the artistic direction sprite mode, is depicted as longer than that of other sprites. This was for artistic purposes to indicate motion, as he was shown in the typical sprite form on the next page.
 * His color is the same as that of Jade Harley's text, a reversal of Jake's text being the same color as Jadesprite.
 * As a result, he's a reference to the RGB color model, the same way LOLAR is modeled after CMYK, this may or may not be a linked to Eridan's light-based science.
 * He only has a fin on one side of his face.
 * It's notable that this sprite managed to remain in existence, as Tavrisprite destroyed itself shortly after being prototyped. This means that despite their mutual hatred, Sollux and Eridan have personalities that are capable of reconciling, though the gesture he made suggests that it's hardly a pleasant combination. Futher dialoge suggests that he came close to exploding once.
 * Despite the fact that he gave Jake the finger, he seemed delighted to see his sprite; he even contorted himself into bizarre positions upon his arrival to express his joy. The sprite however, is less than overjoyed to talk to Jake.
