Starship/WMG

They will have a sequel with Junior's dad in a prominent role.
And boy is he pissed about  Also, Roach will have a bigger role.

Dr.Space Claw killed Junior's mom
It doesn't seem above him to do that and would make sense why she died so suddenly.

The first robot was created by an Astro Boy fan.
And then, after Astro Boy turned evil and killed his creator, built more robots, all designed after famous robots from various media. After all, being attacked by Autobots, a group of robots you were brought up to believe are the good guys, would be much more terrifying and distressing than being attacked by a group of robots with original designs.
