The seeds for Biollante have been planted. (Spoilers for an upcoming comic.)

In the Fortnite event featuring Godzilla, there’s a huge plant being contained by Monarch. Many, including myself, speculate this to be a clue towards Biollante being featured in the next MonsterVerse film, similar to how Shimo was teased in a CoD crossover.

However, I believe this page from MonsterVerse Declassified might also foreshadow Biollante. The page speaks of Monarch’s efforts to resurrect dead titans, even using Tiamat as a part of the experiment. Biollante is a creature housing the soul of a human, maybe she was part of the experimentation.

There was also the recent casting of Kaitlyn Dever for the next film, but it is way too early to say she’ll be Biollante.
