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.

Shiny's out to prove he has what it takes to fight with Thunder. After Shiny shows his moves, Alex gives him a shot with his own solo mission.

Tired of being under Thunder's shadow, Shiny enlists the help of tech savvy Sarge to level up his fighting skills against the terrorizing kaiju.

When kaiju mites attack Shiny and Thunder, Alex and Creed must call on the extermination team. Meanwhile, an alien spy breaks into their headquarters.

Shiny and Thunder head to the other side of the planet to battle a two-headed kaiju. But the spy tries to sabotage the mission and take over the base.

Alex starts to crush on an alien teen genius who crash-lands on Earth after a kaiju battle. But Shiny, Thunder and Creed question his intentions.

Vanessa the spy sends off a signal that summons ancient kaiju to spring up from their underground hibernation and start chaos in multiple cities.

Shiny reveals a clue that helps Alex begin to locate her parents. Vanessa and her alien overlord decide to accelerate their destructive aerial plans.
