From "Avengers: United They Stand: Remnants (#1.5)"
The synthesoids displayed great potential.
Yeah. Too bad they wasted it on Ultron.
My human engrams sense a strange void - an empty feeling. I believe the word for the human emotion is "regret".
Those creatures were made to serve the madness of Ultron. They-they never learned to choose between good and evil.
It is unfortunate, that they never had the chance.
