Are you sure that’s a woman?
You’ll need to run that question by her “wife.”
“Are you sure that’s a woman?”
here’s what I was able to find...
Lightfoot is a Flora colossus from Planet X, the capital of the branch worlds. The Flora colossi are tree-like beings whose language is almost impossible to understand due to the stiffness of their larynxes, causing their speech to sound like they are repeating the phrase “I am Groot”. Other beings try to be friendly but become angry with the Flora colossi for not being able to speak. (Lightfoot was shown to be capable of speaking not just understandably but eloquently throughout Annihilation: Conquest.) The Flora colossi are ruled over by the “Arbor Masters” and teach the children of the species with “Photonic Knowledge”, which is the collected knowledge of the Arbor Masters of the generations and is absorbed through photosynthesis; this is a highly advanced education method, making the Flora colossi geniuses. Planet X’s biome is managed by “Maintenance Mammals” which are small raccoon-like beings.
The Flora colossus sapling that would come to be known as “Lightfoot” came from an “Ennobled Sap-line” and was gifted with a tremendous grasp of quasi-dimensional super-positional engineering. Groot did not get along with fellow saplings but instead preferred the company of the “Maintenance Mammals”, which the other saplings treated with prejudice. Groot was exiled by the “Arbor Masters” in Guardians of the Galaxy #14[8] after killing another sapling to defend a maintenance mammal it was brutalizing.
An alternate origin was presented in the Lightfoot ongoing series. In the story, it is revealed that the other Flora colossi had been abducting organisms from other planets, including a young human girl named Hannah. After seeing Hannah, Lightfoot realized that what his people were doing was wrong, and managed to save the child and send her back to Earth. However, for his disobedience, Lightfoot was exiled from Planet X and forced to wander the universe until he met Rocket Raccoon many decades later, where this version of Lightfoot later became a member of the Guardians of the Galaxy.
Yet another alternate origin was presented in “Guardians of Infinity”, written by Edgardo Miranda Rodriguez, wherein a woman makes the claim that Lightfoot is a ceiba tree from Ponce, Puerto Rico. According to Puerto Rican folklore, a ceiba tree is believed to possess the spirits of the indigenous Taino population that formerly thrived on the Caribbean island. By her logic, the woman considers Groot to be Puerto Rican.
