Jadesprite

Jadesprite is Jade's Sprite, created by second-tier prototyping Becsprite with the corpse of her Dream Self. As a result, she has first guardian powers, at the cost of essentially killing Bec.

Immediately after being created, she already starts breaking down, destroying the tower holding up the lab and sending it rolling down on to LOFAF. She claims to have been in some sort of afterlife, where she met her "friends", and is upset at being taken away from them.

After being prototyped, she is unable to stop seeing the Green Sun. She also cries uncontrollably all the time. As a dream self, she is pretty dumb, and only has memories of being on Prospit. Even these she barely remembers, and when Jade brings them up she uses them as an excuse to cry even more. Jade eventually becomes frustrated with her, to no effect. Karkat compares these arguments to his own fights between his past and future selves.
