The sudden surge of potency in Ashton baffled Atlas. He couldn't believe the mortal was hiding his true strength till now. But in hindsight, no matter how strong his enemy got, they would not be able to defeat him.
His abilities made him almost unkillable, even if the power of death had corrupted him and made his rank fall after his 'death'. His combination of tanky abilities was the reason why he was able to kill even the most fearsome Precursor prisoners after they betrayed him.
"I don't care... now matter what you become..." Atlas laughed, "You still can't... defeat me..."
That's right. The number of broken abilities that he possessed, made it impossible for Atlas to die. Not to mention, his weapon was something the precursors had created.
There was no way a mere mortal would be able to get rid of him so easily. But why was he reassuring himself over and over again?
