Sonic Boom


 * Not to be confused with Remy's version, Light of Virtue.

"That was a Sonic Boom that hit you, not a tank!"

- Guile, Street Fighter Alpha 3 MAX

Sonic Boom (ソニックブーム, Sonikku Buumu) is a special attack. It is a crescent-shaped projectile, and is one of Guile's and Charlie's signature moves.

Description
Input: 

Executed by charging backwards and then pressing forwards and punch, it involves one to two waves of energy released by a quick arm motion. The arm motion varies with the user: for example, Guile's is accomplished by a double arm-cross slash, while Charlie's involves only one arm.

Guile has had the move ever since his debut in Street Fighter II, and is considered one of his deadliest moves. Guile launches his Sonic Boom with both arms, and its range is the same as Hadouken's, though Guile's tend to be a little slower than it. However, it has plenty of uses, regardless of speed, and is very useful in the hands of a pro. Guile's Sonic Boom has huge combo potential, and is often used for mind games. Guile's has a good amount of Stun, and mastering it essential for his various combos, along with Flash Kick.

There are several developed strategies for this move. The slower/weak variation is easy for Guile to follow, so if the foe avoids it, Guile can counter, and if the foe doesn't make a move to dodge the projectile, they'll be hit, and wide open for another setup. The faster/stronger variations are good for assaulting and pressuring projectile-less foes into making mistakes in their approach. The Sonic Boom is the pinnacle of his professional-league victories, and is a major factor in why he is widely considered top tier.

In Guile's return in Street Fighter Alpha 3 MAX, the move, like all other projectiles, are weak in power, stun, and guard breaking ability. The same applies to Charlie.

Sonic Hurricane

The Sonic Hurricane is Guile's Super Combo in Street Fighter Alpha 3 Max, and Ultra Combo in Super Street Fighter IV. Guile unleashes a massive Sonic Boom which whirls in place directly in front of him, dealing significant damage to any foe caught in it.



Charlie
Charlie's are overall similar to Guile's, though they move faster. Though not as useful in Street Fighter Alpha due to Street Fighter Alpha's physics (which hurt its combo and dizzying ability), it is still useful as his primary projectile. Charlie also has Guile's Flash Kick ("Somersault Kick"), which a Sonic Boom can effectively lead into.

Sonic Barrage

Sonic Barrage is Charlie's super combo, involving several Sonic Booms. Charlie has this move in each Street Fighter Alpha game. Of note is that he uses an uppercut, a spinning back knuckle and a reverse spinning kick, demonstrating his mastery of the move.

Seth


As Seth mimics moves from some of the fighters of Street Fighter IV, he thus has the ability to fire a Sonic Boom, with the same command input as the Hadouken.
