Barbara Strauss

Barbara is one in the set of triplets (along with Niki Sanders and Tracy Strauss) who was synthetically given abilities by Dr. Zimmerman. After being separated by her sisters, Barbara appears to have been raised by Dr. Zimmerman as his own daughter. Zimmerman mentioned super strength and super speed upon meeting Tracy Strauss. Considering that Niki Sanders had the ability of super strength, one can assume that Barbara has the ability of super speed.
