Here are the two Resonance Burst forms(inspired from the Command Styles in Kingdom Hearts) of Roy Juanlao. I went ahead and covered him in blue flames and made his eyes glow blue(Fever Raid) and red(Huli Jing) to give him a more demonic, but empowered look. I decided to use pencils for Fever Raid and markers for Huli Jing just to mix things up. Anyway here is the information of the forms below:

Fever Raid: Roy's first Resonance Burst form. While a Level 1 Burst form, Roy's strength and speed increase remarkably. While engulfed in flames of mentality, Roy has greater attack speed and power. Roy can also slash marks of light into the ground that can damage foes in the vicinity.

Huli Jing (romanized: Kitsune): Roy's second Resonance Burst form. As a Level 2 Burst form, Roy holds incredible strength. The flames that grew from his mind become more intense as he grows nine tails from his back, his hair turns blue and his eyes turn red. As a result from his increase in power Roy becomes more bestial, possessing a savage, bloodthirsty, and uncontrollable frenzy. Though he is able to consciously control himself later on, he can very easily become caught up in the pleasure of slaughtering his enemies. When using his state, Roy gives up his sword for more fast, brutal attacks from punches to shredding through foes with his claws. The nine tails on his back can also shapeshift into dragon heads, blades, claws etc. for his use.

Note: The plain white isn't the color of the forms, I just left Roy uncolored so that the flames would stick out more.
