When his master was mutated into the Super Shredder, Rahzar took part in the climactic clash with the combined forces of the Turtles and the Mighty Mutanimals. Rahzar ran afoul of Leatherhead, who used his massive size and strength to easily overpower Rahzar, and dragged him to the bottom of the river, drowning him. In the fifth-season episode, "The Forgotten Swordsman", Tiger Claw orders an annoyed Fishface to retrieve Rahzar's corpse from the river, and has Kavaxas resurrect him. Overjoyed at having been brought back to life, Rahzar finds himself questioning his loyalty when Hattori Tatsu arrives in New York, offering him a place as his right-hand man in his new Foot Clan. Rahzar ultimately remains loyal to the Shredder, but is repulsed and terrified when Kavaxas resurrects him as a shambling corpse. When Tiger Claw realizes that Shredder is only living to serve Kavaxas' will, it is revealed that Rahzar has suffered much of the same fate, as Kavaxas takes control of his body and refers to Rahzar as his "undead warrior". After dueling Tiger Claw, Rahzar falls into a pit to the netherworld, and is not seen again, potentially dead for good this time.
