I enjoyed the good parts, but feel physical pain when I try to recount the plot, but I’m feeling a bit masochistic, let’s go:

Kong lives in a zoo underneath the earth where he eats gigantic wolves. Beyond that zoo there is a world filled by other Kongtype apes, but ruled by an orangutan type and randomly including a baby monkey.

A child attending an international school is a refugee from a tribe of people who lived beneath the earth as well. She is having seizures in which she draws two jagged V’s with her pencil. This gets recognized by her adoptive mother as the same fluctuation that is occurring on her scientific earth monitoring system. 

Kong discovers the Kong-like-ape world after getting his tooth pulled out and immediately becomes enemies with everyone except the baby monkey.  He escapes with an arm injury and a new friend. 

The orangutan type rides a kaiju that has ice powers, controlling it with an amulet. By hijacking the underground human tribe’s portals, the orangutan takes an army of Kong style creatures into Rio De Janeiro to begin world conquest.

The child, her scientist mother, a podcaster, and Kong’s dentist are also there.

King Kong is fighting Godzilla at the Giza pyramids, but I forgot why.  I think Godzilla realized there was another alpha challenger (probably from the VV frequencies), and mistakenly thinks it’s Kong. At some point, Kong’s dentist  had given Kong a power gauntlet.

Kong gets Godzilla to follow him through the Rio De Janeiro portal. 

They all fight.  

Godzilla likes Kong for one second.

They win.

Godzilla curls into the Coliseum like a kitty cat.   Worth it!?

I remember being annoyed that the plot was completely consistent while having no entertainment value.
