Robots presumably don’t have a need to be gendered, at least in most portrayal of robots I’ve seen.
The creator refered to it with a male pronouns, probably because their vision of the character have masculine features. That doesn’t necessarily mean the character itself is male gendered.
No, he’s a robot.
Gender is no one’s slave (other than for kinky reasons)
What does being a robot have to do with anything? He still has male pronouns.
