Okay, I'll get rid of the Gorgo stuff. A different take I could do on the character that I just came up with now is instead of my character being Canadian, he's from North Korea. He would still be an expert in kaiju biology and behaviors, but he was a part of the North Korean anti-kaiju division. He believes he's doing a good job in fighting the kaiju, only to learn that North Korea is trying to weaponize kaiju. My character would then be made to try and train smaller kaiju for military use. But with the help of the South Koreans, he would unleash a kaiju in the lab, causing it to be destroyed with no survivors. Except my character who is smuggled to Japan where he is given a new name and made a member of YATAGARASU.

Let me know if that idea can fit or if I should try something else entirely.
