Kris has pale pinkish skin, dark brown eyes and long black hair that's died blue at the ends and is kept back by her purple stocking hat. She has trapezoidal wire frame glasses. She wears a white short sleeve tee shirt over a black long sleeve tee shirt, both loosely tucked into her torn grey jeans. She sits and stands with a slightly slouched posture.
Kris's sole reason for being seems to be the pursuit of Dr. Zone. She is indifferent and dismissive of anyone lacking Dr. Zone knowledge, hostile and combative toward anyone who is misleading or challenges Dr. lore and is warm and receptive to those who are able to impress her with their own Dr. Zone knowledge.
Not counting her appearance in the title sequence, Kris first appeared in "The Doctor Zone Files" standing in line to see a Dr. Zone movie. At first she is somewhat hostile toward Melissa and Zack for being "newbies". She becomes even more hostile when Melissa and Zack come up with the theory that "Time Ape" and "Dr. Zone" are siblings. Later, when it is revealed that "Time Ape" and "Dr. Zone" are siblings, Kris is impressed and looks toward Milo, Sara, Melissa and Zack approvingly.
Kris reappears in "The Wilder West" when Sara calls her to come see a likely filming location of "Dr. Zone". After taking pictures and posing in front of various backdrops she is dismayed by the possibility that the location is famed due to a horse corralled there named Doctor Zone. Afterwards Kris and the other "Zonies" leave in disgust, completely abandoning Sara.
Kris's relationship with Sara, Milo and friends remains unclear thus far.
