Groot is one of the original members of the Guardians of the Galaxy. The character started out as the companion and best friend of Rocket Racoon but soon became one of the members of the ragtag group of heroes that worked together to help people all over the universe. Of course, Groot has been in every Guardians of the Galaxy movie and has even made appearances in other MCU films. So, how old is Groot in every Guardian of the Galaxy movie?
The original Groot’s age is unknown, but the new Groot was born in 2014 and was only a few months old in Vol. 2. Meanwhile, Groot was around four years old during the events of the Avengers: Infinity War and Endgame. Then, in The Holiday Special and Vol. 3, he is around five to six years old. If you cunt the time he was snapped as lifespan, in that case, he is around 11 years old in Guardians of the Galaxy vol 3.
It is worth mentioning that Groot is unlike other alien species because he grows a lot faster. In that regard, he has shown significant changes in his body in every Guardians of the Galaxy movie he has appeared in due to the fact that he grows faster than other species. So, with that said, let’s look at how old Groot is in every Guardians of the Galaxy movie.
How Old Is Groot In Guardians Of The Galaxy?
The first time we met Groot was during the events of the Guardians of the Galaxy when he was the muscle of Rocket Racoon but was also his best friend and traveling companion. During that time, he was a friendly tree-like alien that was nicer than all of the members of the Guardians of the Galaxy as he went on to work with them to rescue Xandar from Ronan the Accuser, who was going to use the Power Stone to destroy the entire planet.
At that point, Groot was already in his adult form and was likely quite mature not only in terms of his appearance but also his personality. But the thing is that we don’t know how old he was at that time, as the only thing that we know is that he’s been traveling with Rocket for years already.
Of course, near the end of the movie, Groot sacrificed himself to save his friends from a crash, and that’s why the original Groot is now dead. Rocket, however, salvaged a twig from the original Groot and cultivated it so that it could grow into a new Groot. That means that the new Groot, born in 2014, was still just days old at the end of the original Guardians of the Galaxy movie.
How Old Is Groot In Guardians Of The Galaxy Vol. 2?
It is worth mentioning that only around a few months have passed since the events of Guardians of the Galaxy and Guardians of the Galaxy Vol. 2. That means that the Guardians haven’t been together for a long time in Vol. 2, as seen from the fact that that they were yet to form any sort of leadership hierarchy or learn how to work together.
During the events of the movie, Groot was still just a baby, as he was often referred to as Baby Groot. In fact, he struggled to even understand some of the things that people were saying due to the fact that he was still just an infant. As such, he was just a few months old at that time and was yet to show any significant developments in terms of his physical attributes.
Of course, during the post-credit scene of Vol. 2, Groot underwent a growth spurt that allowed him to become an angsty teenager that was quite rebellious toward the older members of the Guardians of the Galaxy. He was likely around three to four years old at that time, as we don’t know how many years have passed since the ending of the movie and the post-credit scene.
How Old Is Groot In Avengers: Infinity War and Endgame?
Set in 2018, Avengers: Infinity War allowed us to see Teen Groot when Thor was rescued by the Guardians of the Galaxy after the destruction of his ship at the hands of Thanos. Of course, he ended up working with Rocket Racoon and Groot to forge a new weapon that he could use to defeat Thanos.
During that time, Groot was still in his teenage form, which was the very same form that we saw during the post-credit scene of Guardians of the Galaxy Vol. 2. Considering that Infinity War took place in 2018, Groot was still just four years old.
However, at the end of the movie, he was snapped out of existence by Thanos. Five years went by between Infinity War and Endgame, where the ones that were snapped out of existence were brought back to the universe by the Hulk when he used the power of the Infinity Stones. That means that Groot, upon returning back to life, was still just as old as he was in Infinity War because he missed five years of his life.
Meanwhile, months after the events of Endgame, Thor went on adventures with the Guardians of the Galaxy, as shown in Thor: Love and Thunder. Groot was still a teenager in that movie, which means that he was around four to five years old.
How Old Is Groot In The Holiday Special?
After the Guardians of the Galaxy parted ways with Thor in Thor: Love and Thunder, the group of misfits returned during the events of The Guardians of the Galaxy Holiday Special, where Groot was clearly now bigger than ever. In fact, he wasn’t only taller but also had a swole body that made him look like he had been spending time in the gym.
Of course, we don’t know exactly when the Holiday special took place, but it is safe to say that it took place around the holiday of 2024, which is a year after the events of Endgame. In that regard, Groot is likely around five years old in this special. But if the Holiday Special took place during the holiday of 2025, then Groot is around six years old.
This version of Groot is called YA (young adult) Groot, as he isn’t even an adult despite the fact that he carries a huge body. This nickname was made clear by James Gunn, who called him YA Groot in one of his tweets.
Of course, during the events of the Holiday Special, Kraglin also said that Groot was still just a kid. And you can see that in the fact that his face still resembles the one that Teen Groot has, and that means that he hasn’t aged a lot despite the fact that he has a swole body.
How Old Is Groot In Guardians Of The Galaxy Vol. 3?
When the trailer of Guardians of the Galaxy Vol. 3 was released, Groot was in his swole or young adult form, as it is clear that not a lot of time has passed since the events of the Holiday Special and Vol. 3. It is possible that only a few months have passed since the Holiday Special, and that means that Guardians of the Galaxy Vol. 3 likely takes place in 2025.
Considering that it takes place in 2025, Groot is likely around six years old in this movie. Of course, you have to take into consideration that he was born in 2014 and had missed a total of five years of his life. That means that while 11 years have passed since Groot was born, he has only been around for six years due to the effects of the snap.
How Fast Does Groot Grow?
Of course, one of the things that you may have noticed is the fact that Groot is bigger than his age would suggest. At the age of six, humans are still just kids that are yet to even learn anything about life. But Groot is already in his young adult form at the age of six. So, how fast does Groot grow?
Based on what we’ve seen from the events of The Guardians of the Galaxy Holiday Special and in the trailer of Guardians of the Galaxy Vol. 3, it is clear that Groot is around 18 to 20 years old in terms of his human years as he looks like an older teenager or a younger adult that still carries the face of a teenager but discovered the gym and carries the body of a grown man.
As such, considering that he might be at least 18 years old in the Holiday Special and in Vol. 3, that would mean that he grows at a rate that is at least three times faster than the growth rate of humans.
But the thing that we also notice is the fact that Groot also goes through rapid stages of growth spurts, as we’ve seen him undergoing massive changes in his appearance. For example, Baby Groot grew up to become Teen Groot quite fast. We can say the same when he became YA Groot from Teen Groot in a matter of months as well. That means that there is a good chance that Groot’s species goes through certain stages of growth spurts that allow them to grow incredibly fast during a short span of time.
