Kate

"Anyone who tries to touch me drops like a human that’s been Tasered. It only downs him for a second, but that’s long enough."

- Kate on her ability

Kate was one of the original Denali “sisters” and an originator of the myth of the succubus. She was a “vegetarian” and led a very peaceful lifestyle. She, like her sisters, loved men – all men, even human men. She had a strong relationship with her coven, along with the Olympic Coven. Kate was known to have a strong mind and had the talent of raising an electric current on her skin.

Biography
Kate, along with the rest of the Denali Coven bar Irina, attended Bella and Edward's wedding. She was described as beautiful and blonde. She along with Irina and Tanya were orphans, as their mother, Sasha, was killed by the Volturi for creating and harboring an immortal child. Carlisle explained that from that point on Irina, Kate and Tanya became purists for the law.

She along with Tanya, Carmen and Eleazar were called upon to be witnesses by the Cullens to prove that Renesmee Cullen was growing. Kate along with Zafrina, helped Bella to project her shielding power in hopes of shielding more people from the Volturi during the final confrontation. During their practice sessions, Kate shocked Edward with a powerful electric current she could generate onto her skin as a way to motivate Bella. She seemed to develop an attachment to Garrett during her time at the Cullen household. Kate was present during the confrontation between the Cullens and the Volturi and was ready and willing to fight. She was also forced to watch as her sister Irina was killed. After the Volturi fled, she and Tanya were left to grieve for Irina. However, she also gained a mate, the nomad Garrett who had ruby eyes and long sandy hair that he kept tied back.

Personality and traits
Despite being outwardly cheerful, Kate appeared to have a strong dislike for Jane of the Volturi, eagerly awaiting her chance to inflict actual physical pain on her when the opportunity arrived due to Bella's help. This would appear to contradict her earlier statement about her gift and how she was not sadistic with it the way Jane is much to Bella's suspicion. However, this reaction may have occurred due to her hatred of Jane. Kate was also fairly strong minded and gets easily angered.

Powers and Abilities
Having the powers of normal vampires, Kate also had an extra ability. She was able to generate an electric current on her skin powerful enough to incapacitate a vampire. She has compared this to a human being Tasered. Kate's power was strong enough that the Volturi offered her a place among them during the Cullen's confrontation with them.
