In the third movie...
Kong and Godzilla should be lovers living together. Lots of monster on monster love.
shareI rather see Godzilla and Kong get the power of speech so they can talk to the humans
shareThen the conflict will be misunderstanding of human languages and both Kong and Godzilla's anger management issues. For the voices
Kong - Robert De Niro
Godzilla - Jamie Foxx
Other monsters will also speak such as
Mothera - Akwafina
King Ghidorah (each head will be a different actor) - Adam Sandler, Anthony Hopkins and Morgan Freeman
