For example when you are controling Gogeta and you press (not hold) "left" and "circle" You do the "BIG BANG KA-ME-YA-ME-AH" But sometimes it may hit your opponents but the power may seem too less.When you hold "left" and "Circle" It gives full power , but sometimes your opponents may seem to dodge it for the time it takes.There is a way you can do this quickly.just click "R" and then press "left" and "circle".
