It could be:

Alex is chasing some demon-alien thing and it travels into hyperspeed. Alex follows it, but gets trapped in a surrounding Universe, Zero's. They think eachother is the enemy and fight, only to get broken up by the demon from before. Then, they fight him, get beaten. The demon flies off to absorb a large power core to blow up the universe, so the two have to stop him.
