Zaacro & Raiti

These shape shifters transform into Namekians and trick some of the Z-Fighters into thinking there planet is Namek.
Form 1
Zaacro and Raiti are shape shifters trapped on a deserted planet. After seeing Gohan, Bulma, and Krillin land on the planet, they fool them into thinking that they are Namekians and the planet is Namek. They lead them on a wild goose chase hoping to steal an opportunity to escape the planet on their spaceship.

Form 2
This is Zaacro and Raiti’s true form. Once in this form they gain no power ups or anything like that. Transforming into this state is very easy and requires very little time.

Master Roshi

The early master and friend of Goku and Krillin is very strong considering he is only human and is able to transform in a matter of seconds.
Form 1
This is Master Roshi’s normal form. In this form he’s pretty strong considering he’s only human. Even when he fights people he stays in this form because he knows how the muscle increase can slow him down.

Form 2
When Roshi is preparing do use the Kamehameha Wave he powers up into this form. He doesn’t have to transform to perform a Kamehameha but they are much more powerful when he does. This transformations takes only a matter of seconds and only a few people have ever seen him transform.
