Flora Colossus Physiology: Groot is the member of an alien race of humanoid trees and as such, possesses various abilities unique to his species.
Regenerative Healing Factor: Groot has been seemingly killed on three occasions, each time regrowing from a sprig. This may be a major contributor to his botanopathy.
Size Addition: Groot can grow at an extremely advanced speed at will, growing to his normal size from a sprig, or growing from his normal size to a giant form.
Plasticity: Groot has the ability to stretch his limbs for long distances and reshape them for a variety of tasks. He normally takes the shape of a large tree-like humanoid, but can also weave his limbs into a dense tangle of vines. He can grow individual limbs to currently undisclosed lengths, allowing him to have stretching powers, similar to Mister Fantastic. This may be related to his cellular regeneration and his control over plants.
Superhuman Strength: Groot's tree like form provides him great strength. His strength allows him to overpower Armadillo.
Superhuman Durability: Groot's hide is composed of wood dense enough and durable enough to make him immune to most conventional weapons, including gunfire and fire which would consume most woods.
Chlorokinesis: Groot especially has the power to control other plants, or his own physical form, therefore he can turn his hands into blades, or grow in size altogether, or even use that power to heal himself from fatal wounds.
Healing Power: Groot is able to heal others. While the full capabilities are unknown, Groot was able to rid the Gardener of poison within a few seconds.
Genius-Level Intellect: Groot has received the finest education from Photonic Knowledge of the Arbor Masters. He was highly intelligent and has a tremendous grasp of quasi-dimensional super-positional engineering. Again, allegedly, as reported by a man openly known as "Maximus the Mad".

Weaknesses[]
Language Barrier: To most people, Groot appears to only say "I am Groot." This made communication with most people all but completely futile. Maximus the Mad asserted that whenever Groot was saying his trademark "I am Groot!" he had actually been saying any number of things. It was the hardened nature of Groot's larynx that causes people, who are oblivious to the subtle nuances of his speech, to misinterpret him as merely repeating his name. After spending some time with Groot, certain people such as Rocket Raccoon were able to pick up his nuances, and understand him.
