I never said Murphy is limitless!!
Murphy can absorb, store and process light. His energy capacity is virtually limitless, he is able to wrest control and manipulate light for a variety of purposes
I'm uh, pretty sure the word limitless means limitless.
CONTRADICTIONS!
I still think the character is a bit OP, what with being invincible and having complete and full regeneration, I've always hated those abilities.
What would happen if your character was against someone like the Handyman, someone who likes to break your will. When this character's will is broken, what's to stop him from using full regeneration then?
Like GT said, if it was some form of enhanced regeneration it would be fine, but having complete healing is stupid. Super-man-esque amounts of power (I hate super man, there can be no character development is the character is already perfect).
And what about a "new moon", where the moon is completely dark, would you still be able to draw your power from the nothingness?
Darkness usually overrules light, dark attacks SHOULD be more damaging than most other attacks, would make for some nice analogies and plot as well (even if a bit cliche).
I still don't like the character, and am not renouncing my "aye"
