Ah, so the Mandos I love, which are wanked beyond beilif
It's been established in EU that Mandos can fight and defeat Jedi on a equal playing field.Ok, now in fairness that's also power wanking, just for Mandos instead of Vader.
Mandalorian Wars?
Neo-Crusaders?
Mando mercs employed by the Sith Empire during their war against the Republic (SWTOR)?
Jango is just a descendant of these Jedi killing mercs. It's in his blood.
