Everybody loves him, but nobody really understands him…and not just what he’s saying, either! Quick—where did Groot come from? What’s the name of his species? How did he meet Rocket Raccoon? If you don’t know the answers, you’re not alone.

The history of Groot weaves a complex web. Having started as a minor character, the talking tree finally received more frequent opportunities to shine in the wake of the first “Guardians of the Galaxy” film. Now he stars alongside the Guardians, his best friend Rocket—and in his own solo series!

On September 27, writer Christopher Hastings and artist Flaviano present the conclusion of I AM GROOT with issue #5!

But before we reach that ending, let’s go back to where it all began for the character. Groot’s story has to be pieced together—and while it doesn’t come to light chronologically, it’d probably be easier to hear it in the order that it happened to him in.

Okay, are you ready? Say it with me: I! Am! Groot!

Groot’s childhood exile

GUARDIANS OF THE GALAXY #14, written by Brian Michael Bendis with art by Nick Bradshaw, explained Groot’s origins for the first time. Framed as a kind of nature documentary, the story explained that Groot originated as a Flora Colossus from Planet X. The book illuminated the social order of the planet, with the Flora Colossi ruled by a monarchy and an elite group called the “Arbor Masters.” Together, these leaders teach children—called saplings—via a method known as “Photonic Knowledge.” In this process, the accumulated knowledge and experience of generations of elders gets psychically absorbed by the young through a kind of photosynthesis; this ultra-advanced educational practice provides the Flora Colossi with genius level intelligence.

The planet’s biome gets tended to by subservient “Maintenance Mammals” (small, squirrel-like creatures) forced into slavery in service of the Arbor Masters. In his youth on Planet X, Groot finds an unlikely friendship with these oppressed animals—and even prefers their company to that of his fellow saplings; Groot doesn’t get along with his own kind, as the adult Flora Colossi regularly kidnap and perform harrowing experiments on other life forms to further their study of the universe. The moral implications of these scientific atrocities horrify a young Groot, as do his peers’ harsh and violent treatment of his Maintenance Mammal friends. Acting on his conscience leads to his banishment from his home world; an unseen narrator explains that Groot got exiled from his people for injuring another sapling as he protected a Maintenance Mammal from attack.

Later, in GROOT #6 by writer Jeff Loveness and artist Brian Kesinger, the tree communicates, via psychic link, to Jean Grey to explain that the original story of his banishment has actually been sanitized…because the mammal he protected from the other saplings proved to not be a Maintenance Mammal after all, but in fact a little Earth girl named Hannah. He reveals that he saw her trapped and terrified by his people and sent her home in a rescue pod—then came the consequences.

Doing time

While it remains unknown whether Groot got arrested for unrelated reasons or sent directly to a prison for treason against his people, we next see our heroin this chronology  locked up—in GROOT #2—where his roommate turns out to be a certain anthropomorphic raccoon. Rocket learns to understand Groot and they forge a strong friendship in the process.

Communication between the duo took some time to be established—the result of Groot’s most famous feature: seemingly only being able to say the words “I am Groot.” As explained in GUARDIANS OF THE GALAXY #17 by Maximus the Mad, Groot’s race experiences a hardening of the larynx and vocal chords during adolescence, forcing them to make the same sound over and over.

Angst, Phalanx, and robbing banks

After spending an undisclosed amount of time together in prison, Rocket and Groot receive an offer to join a rag-tag group fighting the Phalanx in ANNIHILATION CONQUEST: STARLORD—written by Keith Giffen with art by Timothy Green. This team becomes known as the Guardians of the Galaxy. At this point in Groot’s life, he claims to be the monarch of Planet X while—surprisingly—speaking normal, if somewhat pretentious, English. During this arc, Groot also volunteers for three separate suicide missions—each time saved from a branch clipping by Rocket.

2008’s GUARDIANS OF THE GALAXY #2, written by Lanning and Abnett with art from Paul Pelletier and Clint Langley, sees Groot’s vocal chords re-harden and his personality settle back into what it had been in his youth: kind-hearted and goofy. The next big change in his life came in the wake of THE THANOS IMPERATIVE in 2011—in a story written by Dan Abnett and Andy Lanning with art by Brad Walker—when the apparent deaths of Star-Lord and Nova cause the Guardians to disband.

In 2011’s ANNIHILATORS bonus story, by writers Abnett and Lanning and artist Tan Eng Huat, Groot returns to Planet X to help liberate his oppressed Maintenance Mammal friends who ran an underground resistance operation. When Groot arrives, though, he’s arrested and tortured for returning after exile and impersonating the monarch. Luckily for Groot, he has the greatest prison breaker in the universe at his side, and Rocket saves him from incarceration. Once the two finish their tearful reunion, they re-start the Guardians alongside Drax—and try to be a force of good in the galaxy.

Rocket and Groot then embark on a road trip to Earth where Groot finds his friend Hannah, now an old woman. This story—in writer Jeff Loveness and artist Declan Shalvey’s GROOT—further delves into the tree’s mind. We hear his psychic words, “Life is not about the shadow you cast on your enemies, but the shade you provide to your friends.”

Most recently, Groot has been spending an unusual amount of time attempting to re-generate from his “baby” state—even missing out on Rocket’s bank heist team in writer Al Ewing and artist Mike Mayhew’s recent ROCKET #1 due to his vulnerable condition. As witnessed in ALL-NEW GUARDIANS OF THE GALAXY, by writer Gerry Duggan and artist Aaron Kuder, the nature of this form and the unique abilities that makeit so are explored in this year’s I AM GROOT series—written by Christopher Hastings with art by Flaviano—where a tiny Groot finds himself trapped on a strange planet in another dimension where no one can understand him. And the finale of this series, issue #5, drops on September 27!

I am Groot

He certainly says an answer enough, but, really, who is Groot? Find the long answer above, but here’s the short one—proven by years of moments and stories, trials and adventures: he’s a friend.
