Inspired heavily by the same-named move in DBZ Budokai 3, this is a Rekka super.
The initial attack is a forward-flying punch. The button-strength determines the distance that Vegeta flies forward.
To complete the whole attack, you have to input P, K, K, P.
After each attack lands, you'll notice that Vegeta flashes white for a fraction. This is an indication to make your next button press,
as each properly-timed input allows for the 'true' impact of each of the attacks. Only with the 'true' impact on all of his attacks
will you be able to perform the 'true' Final Impact and do the most damage.
The button-strength for each of the follow-up attacks does not matter, only the input timing of them.
