Sensor (Jeka Wynzorr) is a superhero appearing in media published by DC Comics, primarily as a member of the Legion of Super-Heroes.
She is a snake-like alien who was later altered by "Hypertaxis energy" into a semi-humanoid shape, retaining her serpent tail but gaining a humanoid upper body.
Jeka Wynzorr is the princess of the planet Orando, which is populated by a ruling class of snake-like aliens and an underclass resembling raccoons. She renounces her position to travel the galaxy and initially uses her illusion-casting abilities to disguise herself as a human. Jeka joins the Legion of Super-Heroes as Sensor and obtains cybernetic arms, which she is rarely seen without.
While battling the Terrorforms on Xanthu, Sensor is exposed to Hypertaxis energy, which causes her to mutate uncontrollably until Ra's al Ghul stabilizes her into a nÃÂga-like form. Sensor becomes reclusive and bitter following her transformation and goes into hiding until the rest of the Legion is enslaved by Universo, whose mind-controlling abilities she is immune to. Sensor and Shikari recruit Ferro and Karate Kid, who were stranded on the planet Steeple, to battle Universo. After Universo is defeated, Sensor co-nominates Dreamer for Legion membership.
Sensor in her original form makes minor appearances in ', where she is among the Legionnaires summoned to help fight the Time Trapper; and Action Comics (vol. 2), where she, Chameleon Boy, and Shrinking Violet unsuccessfully attempt to change the past.
Sensor appears in Adventures in the DC Universe #10.
