Toby's father, Dr. Tenma, is a famous roboticist and head of the Ministry of Science, but has a distant relationship with his son. Dr. Tenma meets the city's obstructive leader President Stone to demonstrate a new defensive robot called the Peacekeeper. To power it, Tenma's friend Dr. Elefun unveils the Blue and Red Core, two energy spheres which have opposing positive and negative energy.
