Groot
Three words, infinite meaning, one very large tree.
Biography
Groot began life in 1960 as a rubbish monster-of-the-month: an invading alien tree from Planet X who spoke fluent, sneering English and planned to abduct a human village for study. Then Marvel's cosmic writers found him in the back catalogue, decided the joke was better if he could only produce one sentence, and turned a forgotten Kirby monster into one of the most beloved characters in modern pop culture.
The Flora colossi are a genuinely alien species. Groot is a monarch and a scholar whose hardened larynx makes every utterance sound like the same three words to outsiders, and his intelligence is far higher than the people around him assume. He regrows from a fragment, absorbs wood and moisture to bulk up to enormous size, and can extend his limbs across a battlefield like a forest deciding to fight back.
His friendship with Rocket Raccoon is the emotional spine of the Guardians, a bond built on the fact that Rocket is one of the few who understands him. Groot has died and regrown more than once, most famously sacrificing himself as a protective sphere around his crew, and the toddler and teenage versions the films produced turned a 1960 throwaway into a merchandising empire.

Comics history
Tales to Astonish #13 in November 1960 introduced Groot as one of Marvel's pre-superhero monsters, complete with a full page of dialogue and a plan to steal a town. He appeared, was defeated by termites, and was more or less forgotten for forty-five years.
Keith Giffen brought him back for Annihilation: Conquest, where he joined Star-Lord's suicide squad and struck up his partnership with Rocket Raccoon. Abnett and Lanning made him a founding member of the 2008 Guardians of the Galaxy and established the I am Groot running gag as an actual language rather than a limitation.
Since 2014 he has carried solo miniseries, joined the Annihilators alongside cosmic heavyweights, and endured several deaths and regrowths. The films' Baby Groot and Teen Groot phases fed back into the comics, which have played with his growth cycle ever since.

Frequently asked
Why does Groot only say I am Groot?
His larynx is hardened and inflexible, so every phrase comes out sounding identical to species that are not Flora colossi. The meaning changes completely with tone and context, and Rocket has learned to parse it. Groot is not simple, he is untranslatable.
Is Baby Groot the same character as the original Groot?
The films treat him as a regrowth rather than the same individual, which is why Baby Groot has a different temperament and no memory of the first film's events. The comics have used the same regrowth logic for decades.
How strong is Groot?
Very. He absorbs surrounding organic material to grow, and at full scale he tears through starship plating and holds his own with Marvel's cosmic heavyweights. His regeneration matters more than his strength, since destroying him only ever slows him down.
What was Groot's first appearance?
Tales to Astonish #13, November 1960, by Stan Lee, Jack Kirby and Dick Ayers. He was a talkative alien monarch who invaded Earth and was beaten by termites, which makes his eventual stardom one of the great comic-book glow-ups.
