Robert Robertson the Third isn't human, and neither is his "father", and Robert Robertson the first is the only human?

Like, maybe Robert the First built the Mech Suit, and then got worried about his inevitable death.

(but he didn't have time- or maybe some other health issue- to have/raise a kid or get a Protégé.)

So instead he created a wildly advanced humanoid robot to act as his son/successor, meant for replacing him after his death.

(Or maybe he got magic people involved, so it's like a technology-magic robot-golem hybrid or something (lol, sentience through magic > the electrical consumption that a fully tech based AI system would require)?)

This worked, and once Robert the Second had been the Mecha Man for a while, he decided he should also create a 'backup'/successor/"son" for if he inevitably got destroyed.

With the advancement of science, maybe he even managed to make his "son" some sort of android that could simulate the appearance of 'growing up' like a human. So he started out looking like a kid, but over time his mechanisms would de-compact slowly into a fully adult form

(He could also use some science-magic stuff to make him a robot-golem hybrid thing, like Robert the First did for him, too.)

This, obviously, adds a whole new layer of angst for Robert the Third about being a hero and not really having another choice considering his entire existence and all that stuff. so on and so forth.

It would also make the whole 'same name passed down from generation to generation' thing make a fun new kind of sense.
