Super Perfect Kaio-ken

Super Perfect Kaio-ken is an enhanced variant of the Kaio-ken used by Cell in Dragon Ball: A New Deviation - An Alliance of Former Rivals.

Overview
The Super Perfect Kaio-ken, like the normal Kaio-ken, multiplies the user's base power level by a certain amount depending on the multiplier. As a Bio-Android, however, Cell is able to modify the cells of those he possesses, affecting the techniques he learns from their cells. In the case of the Kaio-ken, Cell modified it to the point where the technique can be used for extended periods of time and the user can increase the multiplication of the technique as he/she fights, up to a certain point. Despite the lessened drawbacks of the Super Perfect Kaio-ken, it does have its limits, and after a long beam struggle with Super Saiyan 2 Vegeta and Gohan, Cell dropped back to his base form.
