I would assume that machines can naturally carry more weight than humans. But what if he is stronger than zarya? Maybe he has the strength to carry her lazer gun in only 1 hand.
What if he could channel the iris through it and give a massive kamehameha like blast?
Zenyatta could be OP if he gave up his peaceful ways.
You had me at kamehameha
“Step into the Iris… and PERISH”
I mean, half the time he’s carrying his entire team on his back, so I think we can safely assume he can lift a lot.
If I remember correctly her most carried weight was the tatto number on her shoulder…
Can’t remember the number tho… 
There’s literally statues flying in Nepal. I reckon he can lift tons with the that floating tech thingy.
Its somewhere around 526kg.
Assuming zen can curl that then he would destroy her
A whole hog.
I dont think mechanical arm of same size can lift more than human arm
You would be surprised how strong they are. Thinner metal bars make the bed frame to support the bed, and the weight of two americans which is around 526kg
Its not about metal thickness, its about engine/muscles.
We would have mechanical arms everywhere if they were strong enough at same size.
But this is in the future where tech is more advanced.
Actually, considering how strong are gorillas (I think one can easily flip over a 1500kg car), Winston should literally one-punch most heroes in the game. Like Doomfist 
look at me profile picture thing.
You are a real hero mate!

You dreams are real
He can’t squat for s**t though
