Nildon

Nildon is a Saiyan born on Planet Vitalia. He is the younger (and shorter) twin brother of Alex and the second-best friend of Tori.

Transformations and Power
At the start of the story arc, his power level was around 21,000,000, just strong enough to equal Kristen, a member of Drake's Gang. However, he has since become much stronger, and is able to rival Androids 17 and 18, with a power level of 250,000,000.

Super Saiyan
He achieved this form when he witnessed Alex on the verge of death against He Nan. Having had enough, he burst forward, as a Super Saiyan with a power level of 270,000,000.
