Elena Validus (A90 Timeline)

Elena Validus is a is a Plumber's kid who served both as an ally and enemy to the heroes in the series, as well as one of Ben Tennyson's love interest. She was first introduced in the live Ben 10: Alien Swarm. In Ultimate Alien, she has medium length black hair, black eyes with long lashes(possibly mascara). She wears a white lab coat over a v-neck black mini dress and black flats while in Alien Swarm, she wore a red leather jacket over a black shirt, dark blue leather pants and black heels. When she was out with Ben, Gwen and Kevin, she had red lips.

Powers and Abilities
When first introduced, Elena was, unlike most Plumber's kids, depicted as 100% human and had no natural powers. However, she was mentioned to be a great athlete, Ben describing her as their school Soccer's team's MVP. She was also shown to be an exceptional martial artist during the fights against the nanochip's human hosts, which might be explained by her father providing her with basic Plumber training similar to Ben's. In Revenge of the Swarm, her former instructor at the Plumber Academy mentioned she would have become a great Plumber.

Since Elena was transformed into a Human/Nanochip hybrid form, she demonstrated the ability to control the Nanochips, using them to fulfill her deepest desire (in this case, her previously repressed crush for Ben). She could shape them at will, creating various structures such as copies of Ben's car or clones of her father she used as minions. She can also use them to animate buildings and control technology. Since her body is essentially made of Nanochips, she also has the ability to change her own appearance at will, and control her form to produce tendrils and melee weapons to use.
