As an adult, Groot eventually found himself wandering off into Kree space. He was soon discovered and captured by Kree soldiers.

Groot formed a friendship with fellow prisoner Rocket Raccoon
and was added to a strike force led by Star-Lord. The primary objective
was to launch an attack on Hala in an effort to defeat the Phalanx.

During
the battle, most of Groot’s body was destroyed. A small twig from his
body broke off during the conflict, which Rocket rescued and carried
with him. Groot can eventually regrow his body to its normal size.

Powers And Abilities

Flora Colossus Physiology:
Groot belongs to an alien race of humanoid trees, and has various abilities that are different from most members of his species.

Regenerative Healing Factor:
He
has appeared to have been killed on at least three separate occasions,
and has managed to regrow himself from a sprig every time. This could be
a key factor in his botanopathy.

Size Addition:
Groot
can increase his size very rapidly, seemingly at will. Groot can grow
from a small sapling to his normal height, or grow from his normal
height into a giant.

Plasticity:
He can
also grow and stretch his limbs for different tasks. Groot is usually
seen as a tall tree-like humanoid, but he can also twist and bend his
roots into just about any size or shape imaginable.
Expanding his
limbs to various lengths gives him the appearance of having stretching
powers. These powers look somewhat similar to Reed Richards of the
Fantastic Four. This ability may be due to Groot’s mastery over plants
and his ability for cellular regeneration.

Superhuman Strength:
Groot’s
hardened body also gives him superhuman strength. He’s able to resist
attacks by Armodillo and other villains with strong outer shells or
armor.

Superhuman Durability:
His “skin” is
composed of wood fibers that are durable enough to withstand most
standard weapons. This includes laser beams, gunfire and fire that would
normally char or destroy other kinds of wood.

Chlorokinesis:
Groot
can control other plant life in addition to his own body. He can use
these powers to heal himself, grow his body and convert his limbs into
powerful weapons during battle.

Healing Power:
He
can also heal others. While the full extent of this capability is not
yet known, he was able to heal the being known as the Gardener from
poison in mere seconds.

Genius-Level Intellect:
Groot
received only the best education from Photonic Knowledge of the Arbor
Masters during his time on Planet X. He is reported as being extremely
intelligent and has vast knowledge of quasi-dimensional super-positional
engineering, according to the Inhuman known as “Maximus the Mad.”
