Ok I'm going to say here since a lot are using jango and boba if any of you watched the clone wars or read about it you would know Jango stole Mando armor HE ISN'T A MANDO. Same with boba he is merely a cloned BH
Jango was adopted by a Mando and raised as one? I assume you're talking about the clone wars tv series, as it certainly doesn't say in the film that he'd not mandalorian. His being mandalorian is mentioned throughout the entire Republci Commando series, and probably in a few other places.
