He is also a playable character, exclusively in Jet Set Radio Advance.
DJ Professor K narrates most of the game's story (Combo narrates the flashbacks in Chapter 2). His broadcasts are also one of the only sources of information about the events and characters in the game. He often talks between missions, as well as provides comic relief.
At the end of the game, Professor K is told by someone off-screen that they don't believe the story he told actually happened. His response to this criticism is vague, "Okay, okay, sure".
In the Game Boy Advance port of Jet Set Radio, Professor K plays the exact same role as he did in the console version. However, once the Final Stage is beaten, he becomes a selectable player character. He is located between Garam and Beat on the character selection screen (he cannot be seen dancing like the other characters, only his picture appears).
In Jet Set Radio Future, his role as narrator and comic relief in cutscenes is similar to the first game. However, he also contacts the GG's with mission information while out on the streets. At one point, he gets more directly involved in the story's events when he is kidnapped by the Golden Rhinos.
AppearanceIn Jet Set Radio, Professor K is a dark-skinned man with orange lips and dark brown hair styled into five large, lightning-bolt-shaped spikes that move along with the beat of the songs he plays. He has a goatee of similar shape and color. Also notable are his gold-coloured nose ring on his left nostril, sunglasses with bright blue lenses, and the yellow letter "K" on his forehead. He is always seen wearing a white shirt with what looks like a black tie in a zigzag shape. He also wears gold rings on both index fingers.
In Jet Set Radio Future, his design is altered significantly. His hair and goatee, though similar in style to that of the first game, are now much shorter and white in color (suggesting he may be older). He wears a black shirt and pants with gold sunglasses with red lenses (the same color as his JSR counterpart's lenses in the official JSR artwork), a gold bracelet, a gold necklace, and patterned shoes. He still has the "K" on his forehead, although it's color has been changed to red and it more resembles a tattoo than in his earlier appearance.
