Shielding

Shielding is a technique that is performed when you hold the shield button down, and a bubble of energy surrounds you. Shielding renders you invincible to all attacks except grabs and Final Smashes. A way to solve this problem is to sidestep before the enemy grabs you. While you shield, the bubble shrinks. Some special moves work similarly to shielding, such as Lloyd's Guardian, but they can't be broken. If you hold down the shield button for too long, or if the opponent hits the shield enough to destroy the shield, you will be stunned for a short period of time, but if your opponent attacks you while you are stunned, you are back to normal.

Each character has different stun designs (Example: Goku's paralyzed design has the Dragon Balls swirling around his head his head as if he was dazing off).

Character-specific


Yoshi's shield

has a different shield from the other characters'. He uses an egg for protection instead of an bubble. The egg does not shrink, but instead darkens from white to dark red. Due to this property it protects Yoshi from shield stabbing. However, in the main Smash Bros. games Yoshi was unable to jump out shield which hindered his out of shield options, but in Super Smash Flash 2 he is able to jump out of his shield.

Jigglypuff's shield

Jigglypuff has a large shield compared to her body. However, if her shield is broken the force of the knockback will send Jigglypuff into the air, and without a ceiling, she will be Star KO'ed. This is known as a Shield Jump.

Shield Stab
A shield stab, also known as a shield poke, is the event of finding a damageable portion of a character slightly outside of their shield and striking it bypassing their attempt to shield. This is a uesful technique because it can used to strike an otherwise defended enemy.

Some characters are easier to shield stab then others. Captain Falcon or Samus is to tall for a spherical bubble to cover properly. While characters who are to short or round such as Kirby and Jigglypuff are hard to shield stab for similar reasons.

Some moves are suited for shield stabbing than others. Multi-hit moves like the Mach Tornado when used at their maximum range can deplete a shield with the first few hits and then hit the opponent on the next few. The hitbox shape of a move also affects its shield stabbing viability; Meta Knight's down tilt hits very low to the ground, it could hit the opponent's uncovered feet without touching their shield center.

As mentioned above due Yoshi's unique shield he cannot be normally shield stabbed.

Shield Grabbing
A Shield Grab is the act of grabbing while shielding. It is used to punish attacks when they are blocked because the attacker will be caught in the lag of their attacks and the defender's grab can connect with little trouble. Shield grabs allow a character to get around the delay of dropping the shield.

Due to grabbing input-wise is the same as shielding and attacking at the same time, shield grabs can also be done just by pushing the attack button, instead of pressing the grab button.

Shield Jump
Shield jump is an aspect of ever character's shield. When a character's shield is broken they will be knocked into the air. However, for most characters this is not truly a problem. However, as mentioned above when Jigglypuff's shield is broken she will sent up with enough knockback to Star KO herself.

Dashing shield
Dashing shield is a technique that is preformed by shielding during a run(not in the initial dash animation)which makes the shield slide a short distance. Sliding versions of out-of-shield techniques can come from this, such as dashing shield grab. Dashing shield can work similarly to a dash cancel.

Shield stun
Shield stun is the effect a character experiences when their shield is hit and they begin to slide. During this time the shielding player won't be able to do anything. This becomes a problem when the opponent consistently hits a players shield creating shield pressure. The shielded player won't be able to react and prevent the opponent from breaking his/her shield.

Shield stun formula
Shieldstun frames:

attackDamage = amount of damage dealt after charge is applied

shieldStunMultiplier = custom multiplier for attacks that defaults to 1.0

round((4.45 + attackDamage) / 2.235 / 2 * shieldStunMultiplier * 1.5)

Trivia

 * Both Yoshi and Mega Man (in Demo v0.6) use their own unique shields (Yoshi hides in an egg, and Mega Man used to protect himself by creating a force field).
