Invincibility frame

Invincibility frames are the period of time (measured in frames) during which a character cannot be damaged. Depending on which kind of invincibility the character has, the attack may "hit" or "miss".

Invincibility attacks

• First 5 frames of Dolphin Slash.
• Wolf's reflector, First frame of the attack.
• Thunder, Beginning frames when Thunder strikes Pikachu.
• Rest, Approximately 20 frames after it's released, but before she starts to sleep.
• Ness and Lucas' PK Thunder 2, the starting frames of it.
• Double Team, the time when Lucario is able to strike back and when he strikes back (prevents trap final smashes).
• All Final Smashes grants invincibility at least in the start of it.

Blocking Invincibility

A character with blocking invincibility will be hit by attacks (so the attacker takes hitlag), but will not take damage or hitstun. For example, characters using a Starman have blocking invincibility, as well as characters about to throw someone (this invincibility lasts 8 frames). Other examples of blocking invincibility include:

• The 2 seconds (120 frames) after dismounting a revival platform.
• The secondary Ice Climber for a second when Belay is used.
• The start of Lucas' and Ness' PK Thunder 2.
• The entire duration of Squirtle's Withdraw
• The start of Wario's Forward Smash.
• The start of Squirtle's Forward Smash.

Dodging Invincibility

A character with dodging invincibility will not be hit by attacks. For example, a projectile will travel right through him or her. This kind of invincibility is often attributed to dodges, techs, edge-grabbing, get-up attacks and animations, and certain body parts during certain moves. Since the invincible character is not hit, a long-lasting attack (or very short invincibility time) may still hit the character once the invincibility ends.
