lvl 3 Supers
Mesatsu-Shinkuu-Hadouken
By far and above the best use for this is when you exect a throw. If you manage to execute a throw of your enemy towards the centre of the screen, then you can do a LOT of damage. In any grove but A as soon as you get the throw of and finish the recovery frames IMMEDIATLY do hcb, hcb+hk. As they get up the will get hit by the Hadouken. They will be knocked unconcious. Go over and execute any combo that is high damaging. The one I use is j.hp, s.hp, qcb+lk, dp+hp. If you are in N or S and have a lvl 1 still then use it in your combo. This combo will work once a round at least adn is hard to see coming. It is not abusable but can be used very effectivly if you’re good. It can easily get 10,000 - 13,000 Damage depending on the groove.
Raging Demon
Another excellent use for the raging demon is if you knock your opponent down in the corner and xx it into teleport. The wall will immediatly kick you out of you teleport and yu can xx into Raging Demon. This is extremly hard to see coming. Even harder to get out of.
Shinkuu-Hadouken
Note to remember with this is that you can juggle in the corner after executing it with dp. Better of as a lvl 1.
Sho-ryu-reppa
Not his best lvl 3 and you are probably better of using another one. Nice lvl 1 damage though.
