They created a sympathetic babyface, Kong, and a dastardly heel, the Skar King without having either of them speak.
In their first fight, Skar King cheats by having his partner Shimo interfere and hurts Kong. Kong then has to rehab his injury and call on his old nemesis Godzilla (who in the meantime gets a couple of easy wins over some jobbers) to come help him with the fight.
Godzilla is still mad at Kong about their last fight (which Godzilla won), so Godzilla attacks Kong. They fight and Kong mostly gets the better of Godzilla after he suplexes him into the Egyptian pyramids (yes, this happens), but Godzilla doesn’t give up and just when he’s about to give Kong the nuclear breath, “the voice of reason”, Mothra, comes out and encourages Godzilla to help Kong fight Skar King and his lackeys.
So, Godzilla and Kong (managed by Mothra) start their tag team fight against Skar and Shimo (and some of Skar’s lackeys),and it’s 50/50 for the most part until Skar and his lackeys start to get the upper hand, but then after getting tired of getting ridiculed and pie-faced by Skar… we get a FACE TURN BY SHIMO. That turns the tide and the faces triumph over the heels with Shimo, Kong, and Godzilla all getting to hit their finisher. Kong and Godzilla leave with mutual respect. Godzilla takes a nap and Kong goes to party with the boys.
Oh yeah… and some humans were around for commentary. It might be the best wrestling movie ever made actually.
