That shaved sides of the head Lightning Lad has, in the 1940s, that cut was about lice detection and prevention. Read some yummy Young Justice yesterday. One of the Kids hacked either a Green Lantern power battery, or the Central power Battery. Which on one hand has me amazed at the versatility of a Waynetech tablet, but on the other hand... I doubt that this 11 year old human is the first "thing" in the known universe to accomplish this feat in the last 3 million years. There's probably entire planets leaching off the Oan Will Power grid to keep light and heat on during winter... Which is a cautionary tale since will power is finite and when the universe runs out, the universe dies.
