Thunder Fist

Thunder Fist (サンダーフィスト Sandā Fisuto) is one of C. Viper's special attacks, exclusive to the OMEGA Mode of Ultra Street Fighter IV.

Description
Executed by performing a quarter-circle forward motion and pressing punch, C. Viper performs a punch with shock that hits twice at the opponent. The distance depends on the punch button that was pressed. In the EX version, C. Viper makes two punch with shock.

Tactics
This move greatly expands the combo options for C. Viper. Thunder Fist is cancelable pressing two punch together, just as your Thunder Knuckle and his Seismic Hammer.
