After eating.. some magic rock he gains a boost in strength in speed, blitzed right back.
Deafening roars, fire that gets stronger with his emotional state, fire projectiles and flame to boost his physical attacks and his Dragon Force which makes him 3x stronger and faster.
Will need a new place to go for scans soon
