After fighting his first monster, red robot Shiny blasts into space. But when he meets new bot Thunder on his return, he realizes things are different.

Battling vicious kaiju is only for the bravest. So Thunder brings Shiny back to the base, where young inventor Alex and Colonel Creed test his skills.

To save Alex and the world, Shiny and Thunder will need to team up with Dr. Starface and Creed — and show off the strength of their brotherly bond.
