High in the sky, millions of Xander clone came togther as a means to create a vessel with superior power, alone it was a harsh taske for Xander, but when split up into so many alteration of himself, the burden of the task greatly depleted, and now the ultimate vessel was about to be born.
What was once a massive ball of flesh and crystallized bones was now an abstract-shaped blob of everchanging mass the size of a small home that was shrinking and shrinking as time passed.
As the skeleton system turned inside out, bones were now going inside, and flesh and blood were beginning to form, concealing the exterior with muscles and flesh.
Both of these began to become denser and denser over time until the abstract blob began to take on a more human-like aspect.
As surviving Xanders, they all sacrifice ourselves to enter the fray as all Xander who once stood here as a method to produce the strongest Xander vessel to date.
