Mutant Plant (Annihilation)

The Mutant Plant appeared in the 2018 movie called Annihilation. They're a kind of hybrid plants that has the shape of a human. It is possible but never confirmed that these were in fact one humans that mutated rapidly into flowering plants which would explain their unusual stance, this is likely what happened to Josie as flowers had begun to grow into her skin due to the Shimmers reality warping effects. They were likely killed alongside all life in the shimmer when it was destroyed.
