Make shrink when got hit by an attack. Any attack that hits after he shrinks insta-kills him (touching the poison mushroom also insta-kills him).
and he have to use his down taunt (or pick up a nearby super mushroom) to grow back to normal size.

There should be a Ztar item that looks almost exactly like a normal Star but instant KO's you if you get it.

Tepig's Heat Crash should Crash the game.
's rest lasts until a sound loud enough wakes up.
Bring back the multi grab but make it usable for other characters too
Make Pac-Man and Bandana Dee assist thophys again but instead they are CPU level 99 or Perfect Frame Imput(TAS CPU but fast forwarded enough to be the normal framerate) And they appear 45% of the time each(90% overall)
Remove every character that is not viable in Melee and/or not in Melee. Afterwards make Final Destination and Battlefield Melee Like

Only Goku's Side Taunt should wake her up.

Rings should also fly out from when he gets hit, and he also dies instantly if attacked without any rings

and also make some of the dropped rings scatter on the ground so can pick up to heal.

Yeah and also Firework Explosions are loud too

Should have 12 health (3 hearts x 4 pieces of it) and dies when his health reaches 0 or less.
Final Destination Stage is unlockable by completing classic mode with every character on Insane Mode or by completing Every event in S rank
Fix 's insane upper knockback from Uppercut Arm by adding twice as much knockback.
's Infinite Dimensional Cape should return in Super Smash Flash 2.
's Inhale should OH-KO anyone. Same goes with except Yoshi makes teammates by eating them once they come out of their egg. Example: Yoshi ate Zelda, Zelda breaks free, Zelda is now a teammate of Yoshi. Zelda cannot harm Yoshi, but Yoshi can harm Zelda, no matter the options.

Sonic should run extremely fast to the point of instantly hitting blast zones.

This is f*** brutal lmao

Make all slash attacks kills in an instant. (she IS a balloon sooooooo)

Actually, that should force her to perform the deflate taunt. (Even in mid air)

They should add wavedashing.

You didn't put Wario because that would be a good idea.

Replace every character in the roster with a variation of Mr. Incredible
e.g. Ichigo becomes Mr. Incredible with a sword (Zangetsu), Link becomes Mr. Incredible with the Hero's Bow etc

They should remove the clouds from 's N Taunt.

Give and infinite float
and also put this glitch back as an official feature:
