Here are the usual "Since warcraft 3" Orcs.

Men are between 2.0 and 2.7 meters tall.
In women from 1.7 meters to 2.5 meters.

Almost no fat.

Much stronger than humans "One orc is as strong as 100 human men! And that's normal, there are much stronger orcs."

Good regeneration. "A severed arm or leg grows back in a month."

Extremely strong body. "Dense skin and muscle makes them impossible to penetrate by spears and crossbow arrows! Firearms are very bad."

Quick for their weight.

Weight, from 130 kg in the smallest male orcs, to 380 in the largest and strongest.

Tendons are much stronger and stronger than in humans. Bones are gray because of the huge amount of carbon and micro carbon nano-tubes that they have been growing since Birth.

Reaction speed is much faster than a human. They're just as intelligent as humans. Many are smarter than we are.

Now here's the problem. How do we make them resilient?

My idea is this. Their green skin is capable of photosynthesis and the heat from their bodies throughout the day makes it almost impossible for them to get tired, "But they still need to eat." And I've come up with some kind of "Correct me if I'm wrong" micro organisms in their bodies that trap germs and other debris from the air and process it into food and energy and feed the orcs and their bodies that way.
Is this nonsense?

Is there a problem with all this? Is it possible to make such orcs more resilient than humans? Are my ideas realistic or delusional?
