— Shadow Jago
Shadow Jago is a character introduced in Killer Instinct for Xbox One as a character given to players who purchased a Day One 12-month Xbox Live membership card. He is an (presumably) evil version of Jago, but utilizes the same moveset as him.
In appearance, Shadow Jago is identical to Jago except for a few key changes. His skin is pale blue, he has pupil-less eyes, has chains in place of rope wrapped around his torso, and various articles of clothing are tattered. His facemask is also stylized after a skeletal jaw in the mouth area.
Although his moveset is identical to Jago's, the visual effects are differed in order to reflect Shadow Jago better (the fire in Jago's Endokuken is changed to a black, shadowy effect, etc.).
His voice is also more sinister than Jago's. Even though his voice is different, both Jagos share the same quotes.
