Shenron
(or Shenron the Earth Dragon)

Ok here is what is known when Kami came to earth he created the dragon balls and when those balls are created a statue of a dragon witch is to be the eternal dragon Kami created the dragon out of a dream he had other than that we know he cannot grant a wish beyond the power of his creator ramie he says the same crappy lines over and over and over and over.....ect..ect.. in the very end he disappears when Goku absorbs the dragon balls that's it.

Power levels

Same as Kami's current level
