Reiko
Costume:
Some Costume Tweaks: Spiked shoulder pads, maybe an emblem for Outworld on his chest, perhaps a beard.
Alternate Color: Exchange brown for purple.
BnB Combos: Too lazy to write these up, but I will mention that he'd pull out his spike club at the end of certain combos.
Special Moves:
Ninja Stars: Reiko throws out a large swarm of shurikens. This projectile comes out really quickly, has a pretty large hitbox, and travels quite quickly across the screen. The trade-off is that Reiko has more cooldown time than usual than other characters.
Ex. Ninja Stars: The move name will sound contradictory, but it's mostly for consistency. Reiko throws his spike club rather than the ninja stars here. It's like Shao Kahn's hammer throws, except it's faster and knocks people away rather than dizzying them.
Shadow Stalk: This is Reiko's teleport from MK4, there are two versions one is Down->Up and the other is Down->Down->Up. The Down-Up version functions like Raiden's more or less, except that Reiko moves down through the ground as if he's glitching the game's collision. The other version has him teleporting away from the opponent at max distance on the same side that Reiko was on.
Ex. Shadow Stalk: Functions like the Down-Up teleport, except now it functions like Noob's Shadow Slam. The difference is that Reiko goes for a tombstone piledriver rather than a german suplex
and the move is unblockable.
Flip Kick: Reiko does that weird looking kick special from MK4 where he does a vertical backflipping roundhouse while never moving his opposite leg. This has a big hitbox and comes out really quickly, it's mostly useable for starting juggle combos and as an anti-air.
Ex. Flip Kick: The attack is similar to before, except it now has super armor like Rain's Ex. Roundhouse and launches the opponent farther into the air.
Shoulder Rush: This attack is borrowed directly from Shao Kahn with some nerfs and minor aethestic changes. The differences are that Reiko doesn't have super armor during the move and it take a bit to actually start up. The aura also changes from green to purple.
Ex. Shoulder Rush: Reiko now uses the same attack that Shao Kahn uses, complete with super armor and instant startup.
Aerial Shoulder Rush: Once again, same as Shao Kahns but with nerfs. No super armor and you can't infinite people to death in corners with it. Purple aura, etc.
Ex. Aerial Shoulder Rush: Same move as Shao Kahns, except this time it covers more distance and the infinite doesn't exist though juggle combos are there.
X-Ray:
Chiropractor: Reiko does a bit of kung fu posing as he glows purple waiting for the opponent to physically attack him. If someone tries to hit him, he'll grab their fist as they attempt to punch him and uppercut their elbow so that it dislocates. In the second stage Reiko grabs them by the shoulders and spins them so hard that their spine doesn't keep up and gets twisted up. At the third stage, Reiko simply kicks them in the face as they're done spinning from stage two's attack.
Fatalities:
Sparta Kick(Sweep Distance): Reiko yells "This is OUTWORLD!", then suddenly kicks the opponent so hard in the torso that it flies off the waist without the head or arms.
Ninja Assassinator(Mid-Distance): Reiko taunts to the camera with a shuriken in hands and in a flash launches hundreds upon hundreds of shurikens at the opponent for about five seconds until they become a human pin cushion as they fall over.
