Helpless

There are certain actions that will cause a character to become helpless. In Melee, air dodging caused a character to become helpless. In addition, most characters become helpless after using an up-special attack. While helpless, characters cannot perform any action except fast-falling, and characters are vulnerable to attack. Helpless mode is canceled by hitting the ground, grabbing a ledge, or being hit with an attack other than Fox's Blaster, Mario's Cape, Mario's F.L.U.D.D, or Squirtle's Water Gun.

Additionally, several other special attacks enter characters into helpless mode after finishing the animations of the attacks while aerial.

These moves include:

• Din's Fire
• Dimensional Cape
• Drill Rush
• Egg Roll
• Falco Phantasm
• Farore's Wind
• Fire Wolf
• Fox Illusion
• Giant Punch
• Gerudo Dragon/Flame Choke
• Mach Tornado
• PK Flash
• PK Freeze
• Quick Draw
• Raptor Boost
• Rollout*
• Squall Hammer
• Wolf Flash
• Monkey Flip**

*In Brawl, this move does not cause Jigglypuff to become helpless. **Using Diddy Kong's Monkey Flip does not cause him to become Helpless, but it does prevent him from using B moves until he lands or is attacked.

Landfallspecial and superdashtechnique

In debug mode, the state of the character when landing from this state is referred to as landfallspecial. Because airdodging enters this state, and wavedashing involves airdodging into the ground, when wavedashing was tried in debug mode, "landfallspecial" appeared for the character state. This led some players to believe that the "landfallspecial" designation was specifically designed for wavedashing, and that developers put wavedashing in the game intentionally, further fueling the various debates over wavedashing's legitimacy. At one point, the myth morphed to where, instead of just landfallspecial, there was purportedly another debug mode designation, cited as "superdashtechnique", "superdashattack" or other variants, created solely for the wavedashing animation. All incarnations of this story are false, and should not be taken as evidence that wavedashing was intentionally put or left in SSBM.

In Brawl

Certain third jumps do not leave characters in a Helpless state, and air dodges only cause temporary Helpless status. This completely changes the strategy of many characters.

Characters not put into a fully Helpless state after using their third jumps:

• Mr. Game and Watch
• Pit (If his third jump is attacked out of)
• R.O.B.
• Snake
• Sonic*
• Peach**
• Yoshi
• Zero Suit Samus

*Using Sonic's up-B prevents him from using B moves until he lands.

**Peach's Up-B causes her to pull out her Parasol, which greatly reduces her falling speed. If the control stick is pushed down, Peach will lower and Parasol and fall Helplessly.

All of the characters on this list except Yoshi, Pit, and Peach have no true Helpless state.
