Dr. K is the supporting character of Power Rangers RPM. Doctor K is portrayed by Olivia Tennet. 

Girlfriend Ziggiego Grovera.


Doctor K is the Rangers' mentor who created their technology and also the Venjix technology she is extremely sensitive about the Ranger suits, and gets hostile if someone calls them or even refers to the suits as spandex. She is a genius and also musically inclined, using the violin and keyboard when working and even using them in conjunction with some of her equipment. Although her identity was initially obscured by her speaking through a computer screen and distorting her voice (the Rangers referred to K as "he"), the Rangers later learned that she is actually a teenage girl. It is revealed throughout the series that she was the creator of the Venjix virus when she was abducted by the "Alphabet Soup" government think tank. As a result of her upbringing, she no longer knows her own name ("K" is her government code name), rarely ever leaves her base of operations, is socially inept (as demonstrated by her bluntness with others), and initially only refers to the Rangers by their colors instead of their given names. After the arrival of Gem and Gemma, she becomes more emotionally open, tries a more encouraging approach with her methods, and has begun to occasionally refer to each Ranger by name - with the exception of Ziggy, much to his chagrin. However, she does still apparently think better of him, as she stated, "The five of you are the only family I've ever known. I love you all." It's also repeatedly hinted that, despite how she acts towards him, she does care more for him than she does the others, even making his name her password for her computer. While she is by no means a physical fighter, she can defend herself with her weapons and wits, as well as an enhanced violin. Despite her phlegmatic demeanor, Doctor K has shown an affinity for cute things, as seen by her Zord designs, puppy slippers and pajamas. Ziggy has also stated that she has a sweet tooth, which contrasts from her rather sour personality. After the war, she plans to open a children's school with Ziggy.

One Decade Later

During 2020, Dr. K was contacted by the Red Beast Morphed Ranger from the Prime Universe; whom was hoping her past research on Dillion's cyborg biology could be of use to free his father from Evox's possession. Dr. K regretted that it was too dissimilar, but informed him of the Split Emitters that freed Zenowing, the Dino Charge Silver Ranger, from his evil half Doomwing.

That same year, Dr. K was asked to come visit the Gold Ranger, Nate Silva. It turned out that Evox was actually Venjix, whom he had mutated and improved during a Morph-X experiment a few years back; turns out Venjix wad hiding in Scott Trueman's morpher after his body was destroyed. Dr. K assured Nate that his mistake was no different from hers for originally creating the virus; however, Nate had the chance and resources she did not when Venjix attacked the RPM dimension.
