On his chest, Boba has another important, personal symbol. It features what appears to be a wheatsheaf, a red droplet and a letter of some sort. Some believe this it to be the Mandalorian crest or a symbol of the Fett clan, but in Legends, it was the sigil worn by Jango Fett’s mentor, Jaster Mereel, when he was a Journeyman Protector on the planet Concord Dawn. The meaning behind the sigil’s imagery has never been fully explained, but the wheat likely comes from the fact that Concord Dawn is an agricultural planet, and while the letter could be the Aurebesh symbol for D, what it stands for is unclear.

Jaster Mereel was a member of the Journeyman Protectors, the local law enforcement of Concord Dawn, until he killed a corrupt superior officer and was exiled from the planet. Following these events, he was taken in by the Mandalorians and even became the leader of the True Mandalorians. In their ensuing conflict with the Death Watch, Jaster saved Jango Fett when his parents were killed by the rogue group. Jaster then raised the boy himself until he was killed in the Battle of Korda Six. Afterward, Jango succeeded his adopted father as the next Mand’alor. In honor of his mentor, Jango displayed Jaster’s sigil on his ship and later passed it down to Boba, who added it to his armor.
