A humorous take would be gallons of a "milk" or milk like product poured into the fuel right before takeoff. We did that to our 5th grade teacher. She was driving a different car after that weekend. Even the teachers thought she deserved it.
Armor that has a shield generator(like the droidekas in ep 1,2, & 3) and also protects the wearer from the radiation caused by the shield generator AND uses the raradiation it creates for something.
Watching Godzilla+Kong monster and horror(Nightmare, Friday, Leprechaun) movies. Just imagining what an amazingly entertaining yet completely ridiculous Nightmare in Tokyo movie would be like.
I'm thinking it'll have a third "bad guy" for the two "heroes" to team up and defeat. There'll probably be a couple pretty damn good fights between kong and godzilla, then one will pin the other down and be about to kill the other until out of the blue BAM! ROAR! GIRR! a bigger/badder threat...
