Cosmic overlord, a sentient force the size of entire galaxies, its form made of black holes and collapsing stars, with reality-warping tendrils stretching across the fabric of space-time. Its body constantly shifts between dimensions, each movement warping the very laws of physics. It consumes planets in one universe and reshapes them in another, merging realities. Stars explode and reform as its energy pulses through the cosmos. Armies of god-like beings, wielding weapons forged from dying suns, converge to face it, their ships the size of entire solar systems. It manipulates time itself, causing battles to rewind, fast-forward, and play in infinite loops. As it unleashes the power of collapsing dimensions, galaxies implode, and entire realities blink out of existence.
