I am so lonely
Its from Invincible S3E08 where the villain Conquest confessed about his loneliness right before killing Mark.
I am so lonely. All the other Viltrumites are scared of me. No one talks to me. No one wants to be my friend. They think I am unstable. They send me from planet to planet, committing atrocities in their name. And as i get better at it they fear me more and more. I am a victim of my own success. Conquest. I don't even get a real name. Only a purpose. I am capable of so much more and no one sees it. Some days I feel so alone I could cry, but I don't. I never do. Because what would be the point. Not a single person in the entire universe would care. Take it to your grave. I am so lonely. All the other Viltrumites are scared of me. No one talks to me.

And as I get better at it, they fear me more and more… I am a victim of my own success. Conquest… I don’t even get a real name, only a purpose. I am capable of so much more and no one sees it.

Stand ready for my arrival worm
From Invincible S3E07 when Conquest introduced himself to Mark.
Stand ready for my arrival, worm. You were given orders. You were given time. You were given more leeway than most, and yet, I find this planet unprepared for the arrival of our Viltrum Empire. The Empire anticipated your resistance, which is why they sent me. I am Conquest, and I am your last chance to fulfill your duty.
