This is represented in a Big Groot tattoo.
For all these reasons, Groot is easy to love.
You, Quill, are my friend.
Groot: Groot also known as the Monarch of Planet X is a fictional character, a superhero that appears in comic books published by Marvel Comics.
An extraterrestrial, sentient tree-like creature, the original Groot first appeared as an invader that intended to capture humans for experimentation.
A new Groot was created as a sprig offshoot and went on to accompany the team on their continued mission against the Phalanx, but was one of the team members captured by the Phalanx.
It's a perfect example of just how different the two characters are, since calling Rocket by his animal name is something the original Groot would never have done.
Generally, the audience is left to guess at what he's really saying.
