Protoman

Unless you can't recall the Megaman series, this is my version of Protoman. In my series, this Protoman was inspired by Tokusatsu Heroes, the kind Megaman watches on tv. And just like in the classic series, Protoman has a bad reactor, a shield, his cannon, & he whistles to announce his presence. Koji had a hard time trying to explain why he & Sayaka were adopting a human child, so he ran off. He reappears in Season 3 when Megaman is off fighting the bad guys of Megaman 3. Season 4 reveals he has possession of Great Shin Mazinger (a Mazinger that looks like a cross between Energer Z & Great Mazinger). Tell me if I'm missing anything.
