Ion :Entity of Willpower:

Created at the very beginning of the universe, Ion is one of the many entities of the emotional spectrum of the Green Lantern comics. It was the very first creature to ever will itself to move, and thus it became the embodiment of willpower itself. The glowing green markings on its body radiate the green energy of will.
