A1: Transform into kung fu scooby, then holding the o button on controller shoot his lightening at the dragon. you can also kick him spin kick and it will deplete some of his strength, but the lightening power strike *that you use to bust down the rock doors* does the job... I hid between the airconditioner vents across from the purple light that turns you back into reg scooby and just kept hitting him with my lightening... when you get to over halfway he shoots fireballs at you, so dodge them and remember that scooby shoots his lightening bolts in the opposite direction that you are facing... so make sure to face opposite of dragon and hit him as he goes by.
