I believe Baldr. I'm not sure, but shining so brightly as the Sun and being so attractive are very common characteristics for him as with the names Utu, Azazel, Apollo. In all of his names, he has often been called as the brightest god shining like the Sun.
But in things like Nordic or Indian history, names that were used did not always correlate perfectly as one name per god. Often a name was representative of a type of energy or spiritual concept. And several different gods could work in ways related to this energy or this working that the name is referring to. And also one god could be referred to by many different names as each name relates to a different concept, and the same god works with all of these areas.
