Eddxell child
Edric is the son of two counterparts, making his parents the same person, therefore, he is a child not meant to be born by the laws of the universe.
Edd and Ell are his parents, because of this, Edric looks just like them, has the same personality, and same powers. You can't tell the three apart.
The only issue is that Edric is cola intolerant, whenever he drinks any type of cola he barfs and feels sick.
