zak

Zak feeds on heat, converting it inside himself into electricity.

Even though the robots don't harm Zaku, he still made himself a shelter out of various junk and lives in it (the shelter is actually covered in moss, but that's only on the outside; there's no moss inside).

In the robot uprising, all robots see organics as complete nonentities, while Zack not only sees humans as equals but also loves animals.

Zak works as a mechanic, meaning he can repair or improve mechanisms.

There are only 12.6 hands on the back and 6 hands on the shoulders or below the shoulders
The arms on his shoulders are normal. The arms on his back don't have hands, instead he has a scalpel on one hand, claws on two hands, a laser on the fourth hand, a blade on the fifth hand, and a clamp on the sixth hand.

On the screen, it's black and white, meaning one half of the face on the screen is black with a white eye and a white half of the mouth, and the other half of the face on the screen is white, with a black eye and half of the mouth. But sometimes glitches can appear on Zack's face, '???', facial expressions resembling emoticons or icons, such as '🔇', '❌️', '✅️', etc.

It looks like a regular mechanical robot, but instead of a head, it has a TV with a face on the screen, it has 6 arms (regular mechanical, similar to human arms) and 2 legs, on its back there are also 6 arms, but instead of hands, there are various scalpels for equipment, etc. (yes... it has 12 arms in total), it is 2.97 meters tall, it is dressed in business clothes

Zack is a living robot, but he is kind and has no hostility towards people.
