The big question I have is: "Are we using actual Canon Kaiju? Or the [url=https://youtu.be/Fu62k4K4sQ4]other kind?[/url]" because I have been on a Gamera kick recently and would probably prefer the former, but have some ideas either way.

This would be an original universe, so the 'Ultraman'-like savior would not actually be Ultraman, but I have no qualms if you want to do a "my OC is heavily inspired by X".

On that note, are you considering creating a member of the second branch? There could be multiple ways to go about this. You could have a genetically modified human who grows and transforms into a kaiju, a telepath who mind controls a kaiju, the kaiju can be remotely controlled (Tetsujin) or piloted (Eva-style) through the use of technological control mechanisms/limiters, or some other idea you can come up with.
