A weaker Cell was fine while being at the center of a sun 2000 times more powerful than Earth's

"Magnificent."

At a distance of 215 parsecs from Earth, Cell hovered motionless in the void of space, his voice inaudible against the vacuum. Initially, he had flown without aim or purpose, simply cleaving through hyperspace for the sheer joy of feeling his perfection. But something had caught his attention as he flew...a blue-white supergiant star, tucked neatly inside a diffuse nebula.

When it came to taking a grand tour of space, he decided, this newfound ability was far superior to Goku's instant travel. It allowed him to see everything as he passed, to ponder his place in the wheeling, whirling tapestry of the universe. It was this ability that had allowed the star to catch his eye.

Its name was Omega Cassiopeiae...a nugget of information buried somewhere within the memories he had inherited from one of the frost demons. Even here, more than a million miles distant from its flaming surface, the light was brilliantly blinding. The star was six times heavier than Earth's sun but over two thousand times more powerful. The intensity of its rays caused his pale green exoskeleton to glow vibrantly, light passing through his entire body.

Cell stared directly into the inferno, allowing his regeneration to restore his retinas even as the blue rays burned deeply. Truly, no mere mortal could stand where he now stood, see what he now saw. Looking down, he saw the light of Omega reflecting off his hands and body...against the blackness of space below him, he seemed to be the source of the light. Here he glowed brightly enough to burn out the eyes of any human. But it wasn't enough.

He laughed. "I simply never considered the true vastness of my potential. Gero never had the faintest idea of what he was creating. Even now, I feel that this is only the beginning, an atom of energy in the universe of my power."

The bio-android extended one hand toward the vast sphere of fire. It blazed with such heat an intensity that even a Super Saiyan would have been destroyed—yes, even one of the frost demons would have been incinerated. Yet he, the one truly surpassing force in the universe, was unharmed. Slowly, the blue glow emanating from his body began to fade as he pushed his aura out around himself.

"Hah! Yes, just as I expected."

His aura morphed, then expanded outward as he pushed his energy away from his body. A moment later, a vast purple shield lit with yellow sparks flickered into view around him.

"Now...let me dare."

Slowly, Cell stopped holding himself in one place, allowing the star to pull him toward its surface. The gravity was immense, enough to crush planets...but his face showed amusement, as if coming face-to-face with death was just a game. He picked up speed, falling faster and faster toward the star with arms outstretched.

His shield itself was now white hot, and had compressed down to a tenth of its former size. But Cell, ever confident, continued to allow the gravity to pull him down. Tendrils of white-hot plasma a thousand miles long writhed around him...but his shield flicked them away as if they were nothing but stems of grass. The star was daring him to keep coming, welcoming the challenge to its power. Which would prove mightier?

"How easily these flames would swallow up an entire solar system," he thought. "And yet, even they must bow in submission before the might of true perfection."

Suddenly, Cell could hear again. The roar of the stellar wind was deafening as he plunged through the corona. As he entered the chromosphere, temperatures soared to over 30,000 K...but not a single drop of sweat showed on his brow. He was fully immersed in the heart of the star now, his perfect barrier compressed to mere inches from his body by the overwhelming pressure.

At the base of the convection zone, Cell stood unmoving. Below him, the star was as dense and smooth as solid gold...above him, walls of flame reached out for thousands of miles.

Slowly, he took a step forward, the density of the star yielding to the might of his aura. "Truly, I have exceeded all that Gero could have ever possibly dreamed." His words were quiet against the roar of the blue inferno.

Cell had secretly wondered just how far he could push himself. But this...to walk unharmed within the most fiery violent furnace the universe could afford...was something no one else could do. Was he a god? No, he was more than a god, greater than the mightiest of the gods. The cosmos would kneel before his might.
