Reluctant Treasure Hunters
a Class 3 droid with no class
A droid mechanic (a droid that_ is_ a mechanic, not a mechanic that works exclusively on droids).
B4-NG keeps Crash safe, and their ship Dodge up and running (when he isn’t looting corpses to help finance his upgrades). He is an exceptional, fine tuned, well oiled, precision machine. He is also currently missing.
