Presenting Jade from DC Direct's Brightest Day series 3 AKA Jennifer-Lynn "Jennie" Hayden. To the uninitiated, Jade is the daughter of Allan Scott AKA the Golden Age Green Lantern and Rose Canton - a woman whose split persona is the villain named Thorn - ex-Golden Age Flash villain (Yeah he likes bad girls). Jade's twin is the slightly insane Todd Rice, also known as Obsidian whose Shadow based powers are in contrast to Jade's light-based powers.
Ironically, both Jade and Obsidian gained awareness of their power while escaping from molestation while they were in their foster homes - their mom's Thorn persona had resurfaced and she stole them away from home but fearing that she could end up harming them, surrendered them to foster care.
Jade manifested the ability to create green light constructs akin to the power of her father and the members of the Green Lantern Corp - but not requiring her a ring to focus the energy or the need to recharge. We should note that the source of her power - as with that of her father's - is the Starheart (Which is magic based versus the Green Lantern Corp's science based rings). Jade would go on to become the Earth's first female member of the Green Lantern Corp and was eventually killed in space during the events of DC's Infinite Crisis.
