C. VIPER - SPECIAL MOVES - SUPER STREET FIGHTER 4

THUNDER KNUCKLE

QUARTER CIRCLE BACK + PUNCH

The Thunder Knuckle not only breaks armor but also inflicts a lot of stun. The Light and Medium versions can be comboed after crouching Medium Punch and Kick and both can be useful for punishing opponents who are charging up a Focus Attack.

Heavy Thunder Knuckle is an anti-air attack, and in most cases you can combo into another as the opponent falls.

Thunder Knuckles can also be feinted by pressing the two opposite buttons before the move comes out completely. For instance, to feint a Light Thunder Knuckle, you can try Crouching Medium Kick cancel into Light Thunder Knuckle and then press Medium and Heavy Punch as quick as possible. Light and Medium Feints have limited use but, the Heavy Thunder Knuckle Feint opens up a whole new world of combo possibilities for C. Viper.

BURNING KICK

QUARTER CIRCLE BACK + KICK

C. Vipers Burning Kick is a critical element not only in combos but also in her mix up game. The Light version is useful for avoiding throws, while the Medium and Heavy versions are typically used in the air to cross up the opponent on wake-up.

SEISMIC HAMMER

FORWARD, DOWN, DOWN-FORWARD + PUNCH

For the normal Seismic Hammer, the strength of punch determines where it hits on screen. It can be useful versus projectile characters and also controlling the ground when used properly. On hit, it's best to follow up with a Super Jump Cancel Burning Kick. 

EX Version has invincibility properties and covers a large are of the ground and will typically be used in most of C. Viper's combos.

You can  Super Jump Cancel (SJC) on hit or block into another Seismic Hammer or feint (cancel). 

To perform rapid Seismo's -- repeated seismos on block -- you have to do a seismo, then another but after you do the Dragon Punch motion, press Up-forward to Super Jump Cancel into the next one.
