Star Wars: Boba Fett - Twin Engines of Destruction #1 pg. 4

Dengar has a troubled meeting with Jodo Kast, a young bounty hunter who's becoming famous for his wearing a set of Mandalorian armor, very similar to Boba Fett's. The Corellian bounty hunter contacts Fett, informing him that his new "alter ego" is becoming a highly requested mercenary, thanks to his habit of pretending to be better than Fett himself. Fett, disguised as Sava Brec Madak, hires Kast himself, in order to trap him on Nal Hutta and punish the impostor. Kast (still impersonating Fett) goes to collect the bounty but finds himself with Fett's gun to his head. A violent fight ensues, with Fett finally killing the impostor.
