isaiah initially took up the name slagger, but his father suggested another codename, joto, which is swahili for "heat". during a battle with haze (jarrod jupiter), he was badly burned. before he died, he touched prysm on the cheek, sending out a heat pulse with his life essence into her. later, the h'san natall had repaired his body, although he was a mindless killing machine in this state. when prysm came within close proximity of him, his life essence transferred back into his body and he regained control. together, the titans and superman were able to talk the h'san natall out of further aggression. the team disbanded and went their own ways. joto would later aid the titans during the technis imperative conflict, which also involved the justice league and all past titan members.
