While Toho has plenty of monsters for the Apple TV+ series to draw from, Legendary may not want to pay for the licensing fees when they could just come up with their own monsters. We learned in "Godzilla: King of the Monsters" that the secret organization Monarch was aware of 17 Titans hibernating around the Earth. That is, until Ghidorah woke them up and sent them on a planet-wide path of destruction, before Godzilla took his crown as King of the Monsters and put them in line.
While the Apple TV+ series is set after the events of 2014's "Godzilla," these Titans don't show up until "Godzilla: King of the Monsters." However, Legendary could still show how Monarch came to find out about them. There's Behemoth, the half-mastodon, half-gorilla; Methuselah, a monster that disguised himself as a mountain in Munich; Scylla, the six-legged, spider-like Titan with tentacles for a mouth; and a whole lot more. As far as kaiju creativity, the Legendary team has given Toho a run for their money, so whether it's these Titans or new ones, we'd love to see more monsters.
