Strength was a relative concept.
Ordinary humans were strong compared to ordinary ants, but before cosmic powerhouses like Dormammu and Thanos, they were not even as formidable as ants.
The Celestials' strength was beyond question, but even within the same race, there were stronger and weaker individuals.
Ego was undoubtedly on the weaker side among the Celestials. After all, he had only been born a few million years ago, and during those "mere" millions of years, he lacked both experience fighting others and experience interacting with his own kind.
Ego's abilities came from his racial talents, things he had figured out alone over countless years. How could something developed in isolation compare to embracing the wisdom of all rivers?
Among the Celestials, Ego was practically an infant.
Hayato could also sense Ego's level of power. If he had to find a comparison, Ego was roughly on the level of the Primordial Demon Hayato had severely wounded, and absolutely nowhere near Dormammu. Of course, that was assuming Ego had not yet fully matured.
Hayato had used teleportation on Ego's Planet with Gamora and Mantis, yet Ego had not noticed at all. Hayato had not deliberately concealed his presence; he had merely used it naturally.
Ego's Planet could be said to be part of Ego's body, which showed just how poor Ego's control over his own body was.
It was no exaggeration to say that Hayato could detect the movements of even one extra mite on his body.
Of course, a creature like a mite could not possibly exist on his body.
Hayato and Mantis chatted idly, talking about this and that.
No matter what topic Hayato brought up, Mantis could always kill the conversation at some point. The same thing happened whenever Hayato talked with Drax.
No wonder Mantis and Drax
