Name: Jonny Desmond
Superhero Name: Blue Lantern
Main Ability: His ring can do whatever the wielder imagines, but only if they have shown to have hope in their hearts, and the ring is in the presence of a green lantern ring. Notable is the fact that compared to the other spectrums of light, Blue is the most powerful, having shown to turn back the age of entire stars by billions of years.
Secondary abilities: Flight, Shield (and thus life-protecting aura), and hyperspeed (for intergalactic travel), which are available even without the presence of a green lantern ring. The Blue Ring's presence super charges a Green Lantern's to nearly 200%, whilst nullifying the effects of a red ring, and Blue constructs are the few that overcome the orange of avarice, hope nullifying the greed.
Origin: Jonny's life is not really all that notable, being an orphan after his father's mysterious death. The one thing that attracted the ring to him, was his incredible hope and belief in the idea in that thing's would change for the better. It chose him, and he journeyed to Odym, where his fellow Blue Lanterns trained him mentally for the usage of the ring.
