In short: In the Marvel Cinematic Universe, the character known as Groot undergoes a dramatic transformation. After a sacrificial battle against Ronan the Accuser, the original Groot leaves behind a sapling. This small plant eventually grows into a new version of the character, whom director James Gunn identifies as the original's son.

The character, a flora colossus, has appeared in six films and various television specials as of 2024. While the original Groot perished during a battle on Xandar, the resulting sapling was raised by Rocket Raccoon. This new iteration, often called 'Baby Groot,' eventually grows to a size comparable to his predecessor. This new iteration eventually matures into a teenage version of himself. This older, video game-obsessed version later assists Thor in creating the powerful weapon Stormbreaker.

The character's name carries linguistic depth, potentially derived from the Dutch word 'groot,' meaning big or great, or the Old English noun 'groot,' which refers to mud, soil, or earth. Within the MCU, Groot acts as a vital Guardian of the Galaxy and a loyal friend to Rocket. He is a key member of the Guardians of the Galaxy. He also shares a close bond with his teammate Rocket Raccoon.

Groot's journey is marked by significant cosmic events. He was a victim of the 'Blip'—dissolving into dust alongside half of the universe—before being resurrected five years later by the Avengers. Throughout his appearances, he has transitioned from a small sapling to a massive, bulky being capable of assisting in massive battles, such as the fight against Thanos or the High Evolutionary. He also fought against the High Evolutionary to help his team. During these adventures, he has travelled to various locations like the planet Xandar.

The character's voice and physical presence are a collaborative effort. In the MCU, Groot is voiced by Vin Diesel, with motion capture provided by several performers including Krystian Godlewski, Sean Gunn, James Gunn, and Terry Notary. Other versions of the character exist in different realities. For instance, an alternate Groot worked at a casino on Xandar.
