Combo

Combo is a member of the GG's and alongside Cube are the characters that drags them into an all out war with the Rokkaku Group. He narrates the whole of the second chapter, revealing the true main antagonists of the game.

Appearance
Cube is a tall young black man, who wears a thick gold chain with a Yen sign around his neck.

In Jet Set Radio, he wears a black bucket hat, a black short sleeved shirt over a light lime green t-shirt, wears dark grey pants and wears black and grey rollerblades. He is always seen carrying his boombox.

In Jet Set Radio Future, Combo wears a blue bandana. He has notable blue sideburns and a blue goatee in this version, and wears a sleeveless black vest top with six gray circles on it, possibly designed to look like a speaker. He also wears silver bug eyed sunglasses in this version.

Jet Set Radio
In Jet Set Radio, Combo and his goth friend Cube, are first seen arriving at the GG's HQ with a challenge, much like characters like Yoyo, Garam or Mew but unlike in those cases Combo and Cube want to join the GG's, forcing the player to play as Cube and Combo as they take on Gum and Beat's challenges to prove their worth.

After beating Gum and Beat, Beat allows them to join but asks them why they were so desperate to join the crew.

Combo reveals that he, Cube and their friend Coin had all once been a part of their own gang, when they discovered their turf had been taken over by the Golden Rhino Signs.

On top of this, assassins had been sent after them and worst of all their friend Coin had been kidnapped. Combo and Cube had set out to try and find out what happened to him, but were left with the reveal that Coin's record collection had been destroyed and he was no where to be seen. Hearing about the GG's in Toyko-to, Combo and Cube came there to request help from Beat, Gum, Corn and the rest of the crew.

Combo and Cube are the main characters of Chapter 2, with players only able to select between them for the flashback levels in that chapter, with Combo narrating the entire story during this period.

Combo also narrates the epilogue in the North American and European versions of the game, although this role is given to DJ Professor K in the Japanese version.

Jet Set Radio Future
In Jet Set Radio Future, Combo's role is reduced somewhat, with him being less plot relevant and simply joining the player after challenging them to follow his lead.

Sega Superstars Tennis
Combo has the largest role of the NPC Jet Set Radio characters in Sega Superstars Tennis.

Combo appears in Beat's All-Star move where he grinds across the net spray painting the opponents side of the court, causing them to trip when they walk on the court. He also appears in the Jet Set Radio challenge stages where he will grind across the net dropping spray cans to the player during the tagging mini game. Players can knock Combo off the net by hitting a tennis ball into him.

Trivia

 * Combo's personality is described as 'Violent' but he seems to be more genuinely concerned and curious about Coin's safety than genuinely desiring a fight. He's very thoughtful and even philosophical at times.
 * Combo is the oldest member of the GG's at 23.
