Davesprite

Alternate Future Dave, also known as Davesprite, is Dave from the doomed timeline where he tier 2 prototyped Crowsprite with Lil Cal. He believed the split was the result of John being tricked by Terezi into confronting Typheus prematurely, leading to John's death. Upon splitting from the Alpha Timeline, he and Rose lost contact with the trolls, assuming that they, having achieved their goal of sabotage, had no further reason to contact them. Jade was believed to be killed by her meteor, since John couldn't connect to her. With only two players remaining, and neither of them heroes of Space, the game was unwinnable.

HS 3541 (We first see) Alternate Future Dave on the Land of Heat and Clockwork four months into the future, where he HS 3543 (discussed the deaths of his friends with Rose.) Dave had alchemized some advanced gear including the Timetables and Caledscratch. He was also high on his echeladder, managing to defeat challenging enemies with ease and style.

Davesprite
Dave's Kernelsprite was prototyped with the remains of the Rambunctious Crow by Jade, much to Dave's distaste. In Alternate Future Dave's timeline, it was second-tier prototyped with Lil Cal, a decision he deeply regretted due to its incessant inane laughter.

After learning as much as possible about the game, Dave used his Timetables to travel back to a period right before he prototyped his Sprite for the second time and prevented alpha Dave from prototyping Lil Cal, instead jumping into the Sprite himself after handing over his inventory. He also stopped John from skipping ahead to his seventh gate and getting killed by his Denizen.

As Davesprite, he gained access to the knowledge the game provides to sprites. Although he is supposed to be cagey about his newfound knowledge, he "" and told alpha Dave whatever he needed to know. However, alpha Dave declined to take advantage of the situation, never pushing Davesprite for answers to the game's larger mysteries. Davesprite also retained use of his iShades, as they were the only thing he didn't expel into a huge pile of captchalogue cards before he jumped into the sprite. Davesprite uses orange text while chatting on Pesterchum. He was upset when John called alpha Dave "," although alpha Dave says that "" and that "".

Other than that, Davesprite's personality was just like alpha Dave's, since he was simply Dave from a doomed timeline. He would update Sweet Bro and Hella Jeff while alpha Dave continued his quest. The second-tier prototyping seems to have erased the rambunctious crow's personality entirely, as was the case with Jadesprite, so he displayed no avian traits apart from an ironic "". and a "PEEP" on HS 6271 (his writings on the Armageddon poster).

After Dave stole Caledfwlch from a Crocodile Temple, Davesprite revealed he did the same in the alternate timeline. He defended Dave from a horde of Giclops after Vriska put him to sleep, then used Dave's pendant to release himself in the same way Rose released Jaspersprite.

He then went to track down Bro, and found him in a duel with Jack Noir on the Land of Wind and Shade, and joined the fight. During the fight, Jade entered and prototyped her sprite with Becquerel, resulting in Jack's transformation into Bec Noir. Jack quickly killed Bro and seriously wounded Davesprite. What remained of him was a pile of orange feathers and his pendant. When Jade looked for the Daves in the Incipisphere with her Junior Compu-Sooth Spectagoggles, the goggles didn't count a HS 5103 (certain dead Dave), but still counted Davesprite, despite the assumption he was deceased. All this pointed to his ongoing survival, later confirmed when he HS 5789 (revealed himself) to Jadesprite on the Battlefield, short one wing and wielding a complete Royal Deringer. He obtained this through "shenanigans" involving the denizen of LOHAC, Hephaestus and later had Jadesprite teleport it to dream Dave with her First Guardian powers.

As the meteors from the Reckoning reached the Battlefield, Jadesprite merged with alpha Jade and ascended to God tier. The new god tier Jade that resulted shrunk down the giant meteor threatening them, then proceeded to shrink down the entire Battlefield along with Davesprite and everyone else inhabiting it, including Nannasprite. She took them with her on her voyage through the Fourth wall. He used his sprite abilities to draw on the poster that was sent to Karkat.

One year into his journey across the Yellow Yard he was seen playing the Ghostbusters II MMORPG with John, Jade and all the others on the Prospitian battleship. He has fully recovered from his injuries, even having regrown his missing wing. During the trip he HS 6635 (began) dating Jade, but by the end of the second year had HS 7192 (broken up with her) for unknown reasons, Jade saying "". Afterwards, he began antagonizing John, leaving disparaging notes in the style of his deceased father, and watermarking the sky with his face using sprite magic.

When the Prospitian battleship finally reached the post-Scratch session, landing on LOMAX, HS 7843 (Davesprite confessed to a sleeping John) that he had probably done Jade a favor by breaking up with her, believing himself not to be "The Real Dave". After furthering this monologue to John, he launched into the sky, leaving the ship and the kids behind with only orange feathers, some notes he had written, and some watermarks as mementos of his presence.

He met up with ARquiusprite on the Land of Tombs and Krypton and began discussing things, including Calsprite from his timeline. Davesprite got on well with him because they were both considered lesser to their "real" counterpart: Dirk's AR was a piece of technology that, despite being sentient, was often dismissed in favor of the biological Dirk.

Personality
Davesprite's personality is mostly that of alpha Dave's, with a few differences. He appears a bit more bitter and worn out than Dave, partially because of having been through months of gameplay in a doomed timeline already, and partially because the others don't consider him to be a "real" Dave.

Jade has stated that Davesprite is "" with some slight differences in personality. His rapping style hasn't changed though. He was once described by John to be "".
