Risso Nu, a bounty hunter hailing from Corellia, masterminded an elaborate scheme with the goal of eliminating Boba Fett and assuming his iconic persona.
Risso Nu, who operated within the Core Worlds, established himself as a highly skilled bounty hunter within that region. However, he became obsessed with surpassing Boba Fett and seizing the title of the galaxy's foremost hunter.
On the isolated planet of Ma'ar Shaddam, Nu sought out and recruited individuals who harbored resentment towards the galaxy's top bounty hunter, persuading them to join his cause. Their aim was to exact revenge, while also allowing him to establish his own reputation. Through information acquired from a Kowakian monkey-lizard, he discovered the location and timing of Fett's armor maintenance, identifying a moment of vulnerability.
The group consisted of Toosog, Eermik, Nagyan, and Mudmub, alongside a droid bounty hunter. They waited for the opportune moment when Fett was unarmored and defenseless before launching an assault on the weaponsmith's hidden workshop in a mountain cavern. Despite being heavily armed, each member of the party was defeated by the unarmed Fett. Risso was the sole survivor, and he successfully managed to steal the renowned Mandalorian armor. In a desperate act, Risso commandeered Fett's starship, Slave I, and used its missiles to obliterate the cave.
Assuming Boba Fett had perished in the explosion, he put on the armor and impersonated Fett at a local cantina. However, his newfound fame was short-lived. The real Boba Fett, very much alive and wearing a spare set of armor, made an appearance and severely beat him before reclaiming his armor and identity. Boba Fett chose to spare his life, as a reminder to the galaxy of who was the best.
Nu lived on, resigned to being second best. Before Risso managed to get away from the cave, he was insulted by Fett, who called him "Corellian scum."
