It’s been done.

Reminds me of the apocryphal stories of Jesus as a boy turning a kid who bumped into him into a corpse. https://en.wikipedia.org/wiki/Infancy_Gospel_of_Thomas

Robo Strux (later known as Zoids), heavily-armed robots shaped like dinosaurs with little human pilots. How this hasn’t been made into a movie yet is beyond me.

There’s a sequel coming out soon.

‘Aaron said that Jamison said, “White boy, I’ll kill you,” and then began to open his door and bent forward in his seat as if he were reaching down for something.’ https://www.leagle.com/decision/inlaco20110112194
