like Flash GL is usually undercapped, he operates as a basic PL10 flying blaster, to reach his full combat caps he must allocate the power reserve to reach his full potential

even without the ring John is a very tough customer, being a PL5-6 soldier

the Animated version of the ring never displayed any sentience or other mental abilities, but since it's part of the GL image I've decided to include it. The basic build is from
Taliesin with tweak from
Jab's GL.
The main differences from the Comic book version are the zero Charisma score, the lack of the corps database link and the Variable sensor power (since the ring showed an very variable and undefined sensory abilties)
