Ryu - Shin Shotokan Mode
Do not confuse this form with Evil Ryu. This is a copy of Akuma only with Ryu's character sprite. This form plays exactly like a Akuma, only with some of the moves changed a bit to suit Ryu. The changes are more in the animation department, but some of these slow down the attacks. Ryu gains the attack power of Evil Ryu, but not Akuma. His defense is lowered somewhat due to the fact that this is Evil Ryu not Akuma. He gains some speed, it just so little that you can't seem to notice too much. The combos that can be pulled out of this form is amazing. They are easy to do and can deal some massive damage. There is only one thing to watch out for when using him. The air MP is the same as Ryu's and can mess up Akuma combos.

Combos
D+WK, D+MK, QCF+2P
This is exactly like the Hiryuu Fist form's Shoryu Reppa combo. 2 crouching kicks into a Messatsu Gou Shoryu. This does about the same amount of damage as the Hiryuu Fist form's combo.
D+WK, D+FP, U+WP, U+WK, U+MK, QCB+FK, QCF+2P
This is a massive damage combo that should be used at every chance possible. It starts out with one hit into a launch. Then the 3 hits holding up while you do them so that the MK hits them up a bit intead of downwards. Then cancel the MK into a Gou Tatsumaki Sepnu Kyaku, then cancel the Gou Tatsumaki Senpu Kyaku after 2 hits into the Tenma Gou Zankuu.
QCB+FK, QCF+2P
This is basically the ending shot of the last combo put into a combo of it's own. Be sure to use the FK on the Gou Tatsumaki Senpu Kyaku or it won't work properly.
FF+WP, FP, QCF+FP, QCB+2P
This is the same thing as the Shinku Hadoken combo for the Shotokan mode, but this time it does less hits, but more damage. 2 hits into Gou Hadoken into Messatsu Gou Hado.
