A student of Dr. Paradigm's who suspects that he's not as good-natured as he makes himself out to be. Her suspicions prove right when she rescues the Street Sharks and discovers what he has done to the Bolton brothers. She helps the brothers whenever she can. She also has a younger brother, Malik, in high school who featured in an episode. Lena seemed to have been written out later on in the series. Around the time that the Dino Vengers were being introduced, Lena rarely ever appeared and when she did, her role was reduced to that of a non-speaking background character in brief scenes.
