Kat is who the Power Rangers look to for technical support. She has designed most of the Rangers weapons - and is Commander Cruger's trusted assistant and friend. Her home planet was also attacked by the Troobian Empire, so she has joined in S.P.D.'s fight against evil. She may be just a lab technician, but she can hold her own. Kat is recruited to S.P.D. central command under request by Supreme Commander Birdie. She returns to Earth with a temporary Morpher and becomes the Kat Ranger to stop an old friend with a grudge. Although her time as a Ranger is limited, she realizes the Rangers need her skills on Earth. When Commander Cruger and B-Squad are captured, she is one of the ones who leads the remaining S.P.D. Cadets into battle against the invading Troobian Empire.
