So here's my wippage.

[b][u]Name:[/u][/b] Jen’Nai Sayan
[b][u]Nicknames:[/u][/b]
[b][u]Alias:[/u][/b] Green Lantern
[b][u]Age:[/u][/b] 28 cycles (approx. 24 Earth years)
[b][u]Sex:[/u][/b] Female
[b][u]Appearance:[/u][/b] Resembles a human female in her mid teens, with [url=http://lostcause26.deviantart.com/art/Back-To-School-403009499]blue-grey hair tied in a side-tail[/url] and big, ice-blue eyes. When transformed, she manifests [url=http://i.imgur.com/cOsH2Ox.png]a uniform much like any other Green Lantern’s[/url].
[b][u]Powers/Skills:[/u][/b] Jen’Nai has all of the abilities bestowed upon Green Lanterns by their rings, such as the ability to generate hard-light constructs from the force of her will. 
[b][u]Backstory:[/u][/b]
Technically the Green Lantern of Sector 3026 rather than 2814, Jen’Nai nonetheless found her way to Earth anyway while chasing a fleeing suspect. Once there, she was ordered to stay, if only because of the sheer number of threats to universal peace that the planet seemed to be spawning; with the Guardians rationalising that the local Lanterns would need all the help they could get.
Jen’Nai is a native of the planet Tyrod, and received her ring when she was just a child. In some ways, this has given her something of an inferiority complex; a desire to prove herself after the Corps kept her sheltered for a number of years, not wishing to expose a young girl to the dangers of life as a Lantern until they felt she was ready, and while she has the Will expected of a Green Lantern she can be impetuous, rushing into situations when a more measured approach is called for.
This sheltered existence gave her plenty of time to be educated in the ways of the Corps, and to hone her skills with the Ring. This means that she’s just as competent with it as many of the mature Lanterns, and more than able to hold her own in a tough spot. 
[b][u]Motivation for joining the League?:[/u][/b] She’s mostly there to replace whoever the principle GL was at this point in continuity.

And yes, I know her hairstyle doesn't match between the two pictures and her mask is missing. I'm kind of limited by what's available in the creator I used.
