The Mount Paozu Demons prey on Earthlings and animals native to Mount Paozu, making the area more dangerous than it had been in the past. They ruled over Mount Paozu until Goku's descendant and namesake Goku Jr. traveled to Mount Paozu in order to reach Grandpa Gohan's House where the Four-Star Dragon Ball could be found in an attempt to cure his ailing grandmother Pan. Accompanied by Puck, Goku Jr. met Mamba who had shapeshifted to a human form in order to trick them into trusting her. Mamba planned to murder and eat the two, but Puck's suspicions saved him and Goku Jr. from being killed when Mamba tried to stab them with an oversized Knife as they were sleeping (unbeknownst to Mamba, they had escaped.
Fortunately, Goku Jr. and Puck managed to turn the tables on Mamba and got away. Mamba along with her cohorts Susha and Torga, later confronted Goku Jr. However, as Mamba, Susha, and Torga were chasing Goku Jr., a father Bear, and his cub whom Goku Jr. had befriended, Lord Yao appeared attacking by turning his arm into a cannon and firing a cannonball. Mamba, Susha, and Torga were frightened to see Lord Yao who wasn't pleased by their failure. The father bear tried to attack Lord Yao, but his strength and shapeshifting abilities allowed Lord Yao to subdue the creature with ease. Fortunately, Goku Jr. became enraged upon seeing Lord Yao hurt his innocent animal friends, and much like his ancestor Goku had done many years earlier, transformed into a Super Saiyan. With his newfound Super Saiyan power, Goku Jr. was able to easily overpower and knock out Lord Yao, causing Mamba, Susha, and Torga to abandon him out of fear of the young Super Saiyan.
