"You... how is that possible?" Ego watched Aaron's size, dumbfounded.
This is a move even he hasn't learned yet.
As a Celestial, he did not possess the ability to greatly increase his size. It wasn't that he didn't want to, but that he couldn't.
After all, strictly speaking, he only had one brain and it was a brain that hadn't fully developed.
Normally, a Celestial would scatter seeds throughout the Universe, fusing with Planets that showed signs of life.
As the celestial body grew for hundreds of millions to billions of years, the Celestial would continuously absorb the planet's energy, and at the same time, absorb the soul power of billions of intelligent beings to complete the final manifestation.
But during Ego's growth, only a brain remained drifting in the Universe. He could only rely on himself, independently gathering matter from surrounding debris to grow little by little.
Even now, he has not completed the accumulation that other Celestials had when they were just conceived.
He still only has a brain, no body.
Gigantification? Dimensional armor? Only in dreams.
Soon, Ego realized what Aaron was going to do.
His brain could change its position within the Planet's core at will.
But...
Aaron was preparing to blow up his entire Planet.
Ego's Planet was only the size of the moon. Its diameter was only one-tenth that of Earth, and its mass was only one-eightieth, Compared to destroying Earth, destroying Ego's Planet was undoubtedly much simpler.
Aaron's entire body suddenly ignited with countless high-temperature flames. He did not transform into Surtur's Lava body. But he was still a humanoid Sun, a Giant of Fire.
Any move by Aaron could cause a major earthquake on Ego's Planet.
In Aaron's hand, a sword appeared.
"What is that sword?" Loki murmured to himself.
Odin's pupils constricted. "It's the Twilight Sword."
This was precisely the scene that had troubled Odin for many years, the moment he would be woken up by every night.
However, Aaron was even larger than Surtur and even more powerful.
When Aaron held the Twilight Sword, tens of thousands of meters long, high in the air, Ego watched with splitting eyes.
"No!"
Hundreds and thousands of lightning chains, thousands of meters long, shot out from Ego's Planet. Like living tentacles, they flexibly wrapped around Aaron.
However, Aaron ignored all the tentacles. With a gentle shake of his large hand, the Twilight Sword, carrying the might of gravity, shattered hundreds of tentacles and deeply pierced the ground.
To ensure this sword penetrated deep into the core, he used gravity control, plus hundreds of millions of tons of immense strength. Even a Vibranium Planet would be cut in two with one slash.
Accompanied by a rumbling sound, the entire ground suddenly cracked, and crimson flames burst out from the ground, burning fiercely. The scorching lava incinerated everything,
Wherever the sword tip reached, the surrounding matter was instantly sublimated by the high temperature.
In just a few seconds, the Twilight Sword had already penetrated tens of thousands of meters into the ground, and a terrifying deep hole spewed flames.
Ego's face turned ashen. No matter how he solidified the ground, he could not resist the world-destroying power of that single sword stroke.
But...
Ego suddenly laughed with relief. "Hahaha, yours isn't long enough."
"Is that so?"
Aaron's eyes burst forth with dazzling golden light, and he twisted his hands. An even larger surge of energy poured out along the Twilight Sword.
Ego felt it most intensely. He sensed that the material activity on the Planet was abnormally frantic. The microscopic particles were mobilized by Aaron, condensing into a terrifying force.
The next instant, the entire Twilight Sword turned golden, with energy rays composed of countless particles, intertwined with crimson flames, forming the last brilliant light in the world.
Boom!
The reddish-golden light, mixed with red, pierced through the Planet.
The energy did not stop gushing out. Instead, Aaron detonated it.
"It's over."
Aaron let go, and at the moment the explosion began, he teleported through the channel to the shattered brain, took a piece of tissue, then teleported above the starry sky.
He looked down at this star, which, in the dark Universe, turned into fireworks.
Ego's Planet exploded after being infused with energy, and the remaining brain was completely obliterated by the raging fire.
Ego only had time to let out one last roar and the Universe fell silent again.
Except for the sky full of fragments, it was as if no planet or life had ever existed here.
Aaron did not leave immediately. His sharp gaze swept over the place again and again.
Only after confirming that Ego was hundred percent dead did he absorb the brain tissue.
[Heart of Celestial: Similar ability detected. Fusion completed. Your brain has been further developed, possessing an almost immortal life force, allowing you to live forever even if separated from your physical body.]
[Energy Control: Similar ability detected. Fusion completed. Your proficiency in energy control has further increased, allowing you to almost perfectly manipulate any conventional cosmic ray in the Universe.]
[Matter Manipulation: Similar ability detected. Fusion completed. Your ability to manipulate microscopic particles has further increased, allowing you to reorganize matter more easily.]
[...]
Aaron recalled the scene of absorbing the celestial flower. The abilities gained this time were actually the same, just more powerful.
But thinking about it, it makes sense.
One was Ego's main body, and the other was merely a dormant Clone. They simply couldn't be compared.
'Speaking of which, there's a dormant Celestial at Earth's core, Tiamut. Should I just devour him?' Aaron thought to himself.
Based on his developmental status, Tiamut would be fully grown in a few more years. Moreover, Tiamut was far more special than Ego.
Not only in terms of developmental stage, but also in Celestial genes, there was a world of difference.
The former was one of the most special Celestials, capable of even surpassing the Prime Celestial in the main Universe, with the potential to become an omnipotent being.
Even if Ego fully developed, he would only be an ordinary Celestial.
If he could devour Tiamut, his strength would undergo earth-shattering changes.
"No, I have to wait."
Absorbing Tiamut, who had no power to resist, was not a problem. But this would inevitably put him up against the Prime Supreme Arishem.
In this Universe, Tiamut could be petrified by several Eternal working together, even if it was partly because he wasn't prepared for them,
It also shows that Tiamut was definitely not Arishem the Judge's match.
Aaron currently had a high chance of winning against an ordinary fully-formed Celestial.
But Arishem the Judge... even if he devoured Tiamut, he wouldn't have much chance of winning.
That was an existence that could toy with the Milky Way Galaxy in his hands.
"Indeed, I am still too weak."
Aaron sighed, turned around, opened a spatial channel, and left.
A few seconds later.
Aaron returned to Osborn Industries.
He immediately saw the various magnates staring at him in a daze.
Odin was silent, Thor was stunned, Loki was worshipful.
And Tony, Coulson, and the Military representatives were still in a state of confusion.
Who are we?
What are we doing?
Aaron made a welcoming gesture, a kind smile on his face. "It's all over. Anyone want to come in as a guest?"
"..."
The atmosphere was silent for a moment.
