This is confirmed by how Krillin states that it was weird how Goku always seemed to grow ever stronger after recovering from fighting devastating battles against powerful foes, how Goku is able to learn and tap into Zenkai's power during his gravity training (which in total boosted his power from "over 8,000" to 90,000 in the Namek saga, as 180,000/2 = 90,000), and how Goku's powers again receive an enormous boost after recovering from his battle with Captain Ginyu in the rejuvenation chamber. While the dub incorrectly implies that Zenkais only occur with Elite Saiyans, Goku, whom Vegeta and Nappa repeatedly refer to as low-level trash ("clown" in the dubbed anime), receives them many times. After Vegeta was again near-fatally injured after fighting Recoome, his strength strangely skyrockets enough to have an even power struggle with Frieza's first form (stated to be 530,000), and another, final Zenkai increased his power enough to see Frieza's movements and Death Beams at first, before he begins to put in even more effort.

When Vegeta recovers from his first fight with Goku, his power level went from 18,000 to 24,000, and another was received after being nearly killed by Zarbon's transformed state and healed in a Medical Machine, which the Daizenshuu estimates to have augmented his strength to roughly 30,000.

Zenkais seem to stop occurring after the Frieza Saga (when most of the Saiyans have already become Super Saiyans), but returns for a single instance in the Cell from his botched self-destruction on King Kai's planet, his power amplified to the point that he has high enough amounts of energy surrounding his body to mimic the style of aura that a Super Saiyan 2 has. Examples are half-breed Saiyans, such as Gohan, and the biological menace Cell.ĭuring the Namek and Frieza Sagas, Zenkai is an extremely important element of the series, which allows Goku and Vegeta's powers to increase in order to "catch up" to Frieza and his men. This trait is not exclusive to pure-blooded Saiyans like the lack of hair growth is, as even clones with partial Saiyan genetic data have this ability as well.

The ability is a genetic trait that allows a Saiyan's power to increase substantially after recovering from near fatal injuries. "Full Recovery") is an ability that is genetically exclusive to Saiyans.
