This is a pretty rough match for Cage against a turtle Scorpion. Cage's gait is slow, and a good Scorpion can always seem to keep away from him.
CAGE
Vs turtle Scorpions I like to get near a corner (not in, but near) and throw low green balls. Eventually he will telepunch and put himself in the corner. That's where you want him. Anytime you're in close to Scorpion go wild with punches, jabs, low toes, sweeps, and shadow kicks. Scorpion is definitely in trouble when Cage is close. Jumping in at Scorpion is a bad idea, but if you do, jump punch late as it's harder to anti-air. If Scorpion is silly enough to jump in at you, anti-air him with either a HK, or aaHP/shadow kick. Block all spears thrown within sweep distance, and shadow kick. Golden punches are great in that they make your Cage a tank, and force Scorpion to take the offensive.
SCORPION
Keep your distance. Cage can't beat you from afar unless you trade projectiles. Anytime he throws a green ball, telepunch. Anti-air roundhouse all his jump-ins. These are really the 3 keys to victory in this match. Quickly throw spears when Cage tries to track you down on foot. Up close Scorpion has nothing on Cage except that their sweeps are about the same speed and length. A close spear is a good surprise move, especially right as Cage comes up from a whiffed sweep kick. But be careful coz you're wide open for a counter if the spear misses Cage. Get aggressive if Cage tracks you down. Do crossovers looking to air throw Johnny if he jumps.
I think this is a pretty even match, and a damn fun one for Cage. They both can give each other trouble if played well. I've played all the great Scorpions and always have to work hard with Cage to win against them. Would love to do a set vs Caldwell's Scorpion to really gauge this match. I go at least 6-4 vs all other Scorpions with Cage, but Mike has the best and I believe I would be hard pressed to do that well vs his.
Overall I'd say a 5-5 matchup, very even.
