Hey, one thing Effy... if you want to play Supergirl and say that she is a real native of that planet I am total cool with that. It might be interesting to play up that angle with a 'clone' in the group

Supergirl and Wondergirl will both be PL12. Again keep your Base Attack Bonus and Skills to PL5 levels (i.e. max skill ranks 8). Questions?
For Wondergirl...here is her Offical DC History (change as you will)
History
Wonder Girl is a precocious and outgoing girl named Cassandra "Cassie" Sandsmark. The daughter of noted archaeologist Helena Sandsmark, Cassie became a super-hero over her mother's objections.
During a battle with a clone of Doomsday, Cassie "borrowed" the Sandals of Hermes and the Gauntlet of Atlas from Wonder Woman (who was not using them at the time), which imbued her with super-powers. Donning a wig and goggles, Cassie became "Wonder Girl" twice this way, helping Wonder Woman defeat the Doomsday clone and other menaces. Her mother learned of her adventures and was very disapproving.
Great Zeus
Later, having been summoned to Mount Olympus by the gods themselves, Cassie boldly stole a moment of Zeus's time and asked him to give her super-powers of her own. Zeus was so impressed by the girl's courage and brashness that he did just that - granting Cassie her "fondest wish." Returned to Earth with incredible super-strength and the power of flight, Cassie permanently assumed the role of Wonder Girl. The gift came with one drawback: Due to her mother's disapproval, Helena Sandsmark had the ability to cancel out Cassie's powers.
Begrudgingly, Helena allowed Cassie to continue adventuring, and Cassie receiving training from Wonder Woman, Artemis and Donna Troy (the first Wonder Girl). As a sign of her support, Donna gave Cassie her old Wonder Girl outfit. Cassie doesn't feel she has earned the honor to wear it quite yet.
As Wonder Girl, Cassie trained alongside Wonder Woman and Artemis, learning a host of martial skills and how to better handle her powers. Wonder Girl soon joined the group of heroic sidekicks nicknamed Young Justice. A natural leader, the members of Young Justice often deferred to Cassie's judgment.
When Silver Swan attacked Cassie at her high school, she was forced into battle, thus exposing her dual identity to the world.
Shortly afterwards, Cassie searched for her biological father. At first, she thought it was Zeus, but when she confronted him, Zeus denied the allegations. Cassie's mother encouraged Cassie to locate her father - who was seemingly a normal man living an everyday life. But this 'normal man' was in possession of a specific gift Cassie gave to Zeus - suggesting Zeus had taken mortal form and was indeed Cassie's father. However, both Cassie and Helena Sandsmark remain in the dark about his true identity.
Powers
Wonder Girl possesses enhanced strength, speed and durability as well as the ability to fly. She also possesses a mystic lasso given to her by Ares. The lasso is seemingly indestructible and emits a lightning backlash. (NOTE it is not a truth lasso

)
