(This won't follow the actual story line. This is what is going on inside my head)
Sabre and Galaxy Steve have been betrayed by Rainbow Steve. He is now working with Void Steve, thinking he is on the right path. After Rainbow Steve leaves, Void transports Galaxy Steve away from Sabre.
After Sabre demands to know what he did with Galaxy Steve, Void transports Sabre to the Void. There, Sabre and Void both find out that Sabre is not all what he seems.
What's so different about Sabre, and what will become of this?
Sabre's been in the Steves' world for quite some time. He chose to stay there, with all his friends, and live there for the rest of his life.
But he's staying there for far too long. His power to teleport to different dimensions and realms has become overwhelming and it is slowly taking over his body and killing him from every bone to every organ in his body.
Sabre is now wanting to hide this new secret from his friends, he can't worry them. But what will he do when his friends do find out about his secret? What if his power takes over too much of his body, and it will be too late to save him?
