Flora Collosus

Flora colossus, commonly referred as Groot due to their limited speech (so they [usually] only say "I am Groot"), are a species of plant-like organisms that are/were native to the fictional planet, Planet X, but were also brought to real life Earth through Universe Travel, and are now one of the most common species of humanoid plant-like species of Earth.

Characteristic Traits
Flora colossus are humanoid in form with a thick, robust body structure that makes them almost invulnerable to physical harm.

They have a highly-accelerated healing factor, able to regrow limbs and even their entire bodies from nothing more than a twig. They have complete control over their bodies, able to extend their limbs as vines to reach high places or as whip-like weapons, grow twigs on any part of their body as a threat display or shield, change their body shape, grow leaves or flowers, and release bioluminescent airborne seeds.
