Okay, so I'm asking this purely in regards to the new Disney canon.
From Episode II, we learn that Boba Fett is an unaltered clone of Jango Fett. Then, in Star Wars: The Clone Wars we see kid Boba a few times and he's hanging out with several of the more regular bounty hunter characters. It seems like an obvious way for Boba to follow in his father's footsteps without having his father there to teach him. Then fast forward to the next set of canon things we see him in, and he's working for Jabba and sporting his nice Mandalorian Armor.
His armor is of course very similar to his father's armor. It's really just a recoloring of it. Maybe Boba just kept his father's armor and restored it for his own use.
However, we visit the planet Mandalore in the Clone Wars series several times. We see that in stark contrast from the Mandalorians we know from (now non-canon) sources like Knights of the Old Republic, the Mandalorians are pacifists except for one group known as Death Watch. All of the members of Death Watch don armor that looks strikingly similar to the preferred choice of protection by our two favorite bounty hunters.
My question is very simple. What's going on? What's the connection between Jango Fett and Boba Fett to the Mandalorians during the Clone Wars? Is Jango Fett from Mandalore? It seems like a very strange oversight for the writers of the series to include multiple episodes about both Boba Fett and Mandalore and never draw a connection.
