"Long live... the King..."

After the battle, you should add the ending part where aliens are overseeing the battle. Call them the Vortax, an alien race of superb tech and superior fire power with both their tanks, and their saucers. More or so, you odd to add a villain behind it. I won’t tell you who, you decide that. I’m only throwing ideas.

Most of Humanity saw Godzilla as a hero to mankind but there were some who viewed him as a tyrant who can turn the Titans against Humanity whenever he chooses. Such power could not be trusted into the claws of a Titan they couldn't control so the government decided to scour the World for undiscovered Titans and see if they can be influenced but none have been found, until now.

Doesn't that seem hypocritical of the government of not liking Godzilla "controlling" most of the titans. BUT, wants to control their own titan/kaiju themselves ( And I highly doubt King Kong wants to cooperate with them anyway. )!?

And having them highjacked a high school's vacation cruise, and possibly make them unwilling participants is basically frickin kidnapping!
