Godzilla vs Colossal Titan

I'm in the middle of Season 1, so no spoilers please. I also feel like there can be two crossovers that would work.

1. Godzilla and Mothra wake up to restore the earth's balance by eliminating the titans and protecting the humans, though it conflicts with Godzilla internally because he hates humans for upsetting the balance in the first place in 1954 with the atomic tests in the Pacific.

2. Gamera being reborn to save the humans from both the titans and the Gyaos in his attempts to redeem himself for being absent during the titans first rampages.

(Edit post function is not working well so...)

1(continuation/explaination). In Godzilla Final Wars, an old man explains to his grandson that long ago, man startes a huge fire and destroyed the land. Godzilla will never forget or forgive mankind for their foolish actions. Hence Godzilla's internal conflict with protecting the humans (he won't join the titans, he's more likely to kill both humans and titans) because of what they've done in the past. And why Mothra is with Godzilla, to keep him from destroying the humans.

Colossal Titan is a loser.
