Xander typically allowed the Demon Overlord to absorb his Blood lust to his satisfaction because it was a huge strain on his body. The Demon Overlord thought he was secretly absorbing it but he was wrong, He was being allowed.
The time had finally come, The time for the Ultimate Esper was at hand. Slowly, Xander's aura became yellow.
The Demon Overlord was shocked yet he kept absorbing more of the Blood lust and evil thoughts at an alarming rate.
"Find peace in the body, That is what these transformations have taught me. I now can rely on my own form because this is MY ULTIMATE POWER!!!!" Xander shouted and his Hair became Blond, His eyes shone in the blue that it once was but his clothes remained the same.
The sound of his voice erupted and cracked the ground, It was maddening. Xander gritted his teeth and his Aura became fully golden. Everything ceased and he stopped flaring his aura, He looked just like one of those Characters from a Naruto Manga.
