Davesprite

Alternate Future Dave is the Dave that resulted from a universe where John was tricked by the Trolls into being killed by the Denizens. This resulted also in Jade's death leaving just Dave and Rose.

We first see Alternate Future Dave on the Land of Heat and Clockwork four months into the future, where he discusses the deaths of his friends with Rose. Dave is at a high level managing to defeat hard enemies with ease, as well as having obtained some cool stuff from the Alchemiter.

After learning as much as possible about the worlds Future Dave uses his Timetables to travel back to a period right before he prototyped his Kernelsprite for the second time. He stopped Dave using Lil Cal, instead handing over his inventory cards before jumping into the Kernelsprite himself. As the Kernelsprite he gains access to the games information and promises to share it all with his present day self. He also retains use of his IGlasses.
