Professor Tennet

Professor Karen Tennet is a high-ranking scientist in the GPU. She is the lead scientist of the R@D team, and she develops all of the technology that the Rangers use in battle. (Excluding the Buddy-Roids and Zords, which were invented by Captain Shields and Lieutenant Woods, respectively.)

A socially awkward woman who prefers machines to people, she doesn't always know how to talk to others, but she is dedicated to seeing the Rangers through the war with the Vaglass.
