Notes & Rules Information
Use the power of the enchanted creature as the activated ability resolves to determine how much damage is dealt. If the creature isn't on the battlefield at that time, use its power as it last existed on the battlefield.

The enchanted creature is the source of the activated ability, not Burning Anger. For example, if the enchanted creature is green, you could activate the ability choosing a creature with protection from red as the target.
: This creature deals damage equal to its power to any target."
