I'm bored I'll explain... On the HUD, which is the image on the bottom left of your screen is a blue bar, it has numbers in it, that is your power level. Each character has its own transforming point and you can check these when you go to choose your character. The "CF" bar on the top of the image also tells you if your PL is high enough.. Once it is hit "z" that is the default unless you changed it!
