Since the final opponent had yet to show himself, Khan had planned to hold back, both to keep information about himself a secret and to avoid tiring himself out.
That was a regular battle strategy, not something especially devised for the True Chaos' God. After all, information was power, and Khan needed any possible edge to win against that enemy, no matter how slight it was.
However, Khan's current opponent could turn mere energy into stars, and the other side of the battlefield featured a warrior who could generate enough True Chaos to build a whole universe.
The scales had never been bigger, standing beyond the limits of what a human brain could comprehend, so Khan couldn't hold back. He had no confidence in winning without going all-out, and lives could be lost with each second he wasted in that battle.
