Grogu was a male Force-sensitive Mandalorian foundling that belonged to the same species as Jedi Grand Master Yoda and Jedi Master Yaddle. Grogu was born in the year 41 BBY, and was raised at the Jedi Temple on Coruscant.
Grogu was eventually held at an hideout run by Nikto mercenaries on Arvala-7 during the New Republic Era. While still an infant at the age of fifty years old, he was sought by an Imperial who hired a Mandalorian bounty hunter named Din Djarin to retrieve him.
However, Djarin chose not to leave Grogu with the Imperials and saved him from the Imperial remnant facility. After attempting to hide with Grogu along the fringes of the galaxy, Djarin returned to Nevarro to deal with the Imperials chasing Grogu in hopes of keeping him safe. In the process, Grogu became a Mandalorian foundling and the single other member of Djarin’s newly created clan.
