“I Sense disquiet in your soul, my dear. What it is that troubles you so?”

“I was created with a directive, but even that feels like it is unfitting. I do not enjoy… this. I do not feel like we are in the right. Harming others, seeking aid like this. It is not… not…“ a glitch in their synth. “… not a good purpose. Not mine. Not like… this.“

Zenyatta Appreciation Week Day 01 - (First) (Impressions) (Starting Point/History)

I chose to go with one of my various ideas for Zenyatta’s origins, which is him as a Null Sector Omnic. When the Uprising ended, Mondatta helped him get smuggled out as one of the Shambali, offered him the freedom to choose, then his guidance when he decided to stay, and help in giving himself a new appearance, so he could choose their own path

and then that omnic became Zenyatta.
