Ray is the first and second image

Ray has solar powers like light beams, magma, heat, stuff like that, their super form enhanced those powers directly from the sun.

Pitch while possessing Ray malform that light and purity by turning the solar magic into eclipsed magic. Which is just corrupted light. Pitch is also allowed to malform his body like a symbiote using that black substance you can see on the tip of his tail and seeping from his gloves and boots like an infection.

Pitch also has a super form, it's the pure white form you saw and it also just enhanced his powers and grants him the basic super form powers
