Even though Heat X's post didn't really stop Cubed64 or make sense in anyways, I'll just assume it did, and while he sleeps, I steal the Dagger of Time, stab him in the eye with it, and go back in time to where the all mighty powerful Cubed64 was just a baby, and kill him in his sleep before he ever had a chance to realise what he was capable of doing. I fast forward to time, killing whoever is in the throne, and reclaim what belongs to me.
I then create a huge barrior around me that for whoever tries to step in it, even obejcts and forms of energy, time will stop for them and it, permenently, and will be frozen in place forever. Me and whatever I touch is the only thing not affected by the time magic as I am the holder of the Dagger of Time.
