This is considered by Master Kai to be one of the most advanced forms of training an individual can undertake, it can take years to fully perfect it; as the combined powers of two seperate attacks can take a heavy toll on a persons body, with the extreme case being death.

During his exile, Hero learned of this form and trained continuously to perfect it, but it almost cost him his life during a heated confrontation.
