As you may already know, pressing L1 when you have some Devil Trigger in the Devil Trigger bar will turn you into a devil(duh!!!). BUT, if you let your health get really low(when it turns red)activate Devil Trigger and Dante will jump into the air and become a MEGA DEVIL!!! He's well more powerful and also it will totally fill up your Devil Trigger bar!!! *Note* This will only work with Dante(as far as I know anyway lol!!)
