Background[]
Personality[]
She is a dedicated girl who likes to preserve and value her grandfather's lifetime work and is even attached to his cult objects. She gets very upset if she loses one. She is very smart and creative, as she showed in her adventures with Ben and Rook. Despite of her seriousness, she still doesn't miss a chance to tease Ben and make fun of him, hiding her crush for him. She works hard to fulfill her objectives and doesn't give up even in the most radical situations. She can also express her deepest feelings when she is very happy, like when she kissed Ben twice after he helped her, despite saying that she doesn't have feelings for him.
In Ben 10: Rise of Vilgax, Kai is shown to be now more loving and caring for Ben.
Physical appearances[]
In the original series, Kai had long, black hair and brown eyes. She wore a red shirt, green shorts, brown boots with white socks. She had silver bracelets and a blue ring.
In Omniverse, Kai has grown noticeably taller. She is slender yet athletic in build. She wears a short-sleeved red T-shirt with a red and peach colored sweater. She still has brown boots (now with blue stripes) and her shorts are even shorter now. Her hair is in a high ponytail and she also has a tan earring. She wears brown gloves, tan socks, and a belt.
At the beginning of Benwolf, she wore a knee-length blue dress with red stripes as well as red shoes with white socks.

Appearances[]
Ben 10[]
She first appeared doing a spiritual Native American dance in the episode Benwolf. She was Ben's second crush, but she only took interest in him after he started becoming Blitzwolfer because she wanted to, as quoted, "train and tame him". When she admitted to this, Gwen gave her a stern talking to.
Kai made a cameo appearance in Ben's dream world in Perfect Day, where Diamondhead saves her and a group of cheerleaders from SixSix and Vulkanus.
Ben 10: Omniverse[]
Kai appeared in An American Benwolf in London. Working with her grandfather, they find the secret laboratory of Dr. Jekyll, but are quickly afterwards ambushed by the Forever Knights in their search for Dr. Jekyll's Hyde Formula. While they capture Wes, Kai manages to escape and contacts Ben and his partner Rook for help. Ultimately, they discover the hidden location of the legendary Excalibur.
When removing the blade from its stone seemingly proves impossible even with the Hyde Formula or Ben's strongest aliens, Forever King Chadwick orders his men to kill their enemies. As Ben battles the mutated Forever King, the cave's underground pipes were ruptured and caused a flooding. Convincing the Forever Knights to work together, everyone was able to escape alive.
In Fight at the Museum, Kai comes to Bellwood to host a new exhibit on alien artifacts at the Bellwood Historical Museum. Her decision to invite Ben paid off when an alien thief named Subdora tries to steal one of the artifacts, one of the first that Kai found with her grandfather. Fortunately Ben's, Rook's, Ester's and Spanner's efforts foil Subdora's efforts.
Knowing that Subdora will be back, the four team up and stay overnight with Kai, Spanner being forced to reveal that he comes from a future where Kai and Ben have been married. Thanks to Spanner's efforts Kai and Ben are locked in a room together where the two, despite their best efforts, bond. Later after Subdora's partner Exo-Skull comes in and tears through the museum and takes the "Key to time itself" from the artifact. Spanner takes the artifact itself, leading Kai to believe she has lost one of the most important things in her life.
In the The Secret of Dos Santos, Kai calls Ben to South America to help her track down The Temple of the Sky, an ancient temple with distinct alien origins. Kai soon develops a love-hate relationship with Ben and his antics, particularly his nicknaming her "the future Mrs. Tennyson," simultaneously annoying and helping her locate and get into the temple. Arriving at the temple's treasure Temple Kai encounters a Galvan named Ujin.
Professor Paradox comes in and explains that the artifact the group has found is the final component of a villain named Maltruant, a rouge Chronosapien obsessed with taking over all of time and space. Exo-Skull tears into the room and, with Subdora and Maltruant's help, escape. After disgusting Kai with his remark about how they're going to get married in the future, Ben left Dos Santos in his Time Cycle.
In The Most Dangerous Game Show, Kai is one of several contestants chosen to compete in "The Most Delicious Game" for the chance to marry Ben. She is the ultimate winner, and joins Ben on a mission to free the losers, who have been trapped in the Null Void. After Charles Zenith is defeated, Ben slips on a banana peel and falls towards Kai, and the two accidentally kiss.
