DK N-air is legit.

[Bars]

I've watched so many videos and never see anyone use dk's nair. wtf!? It's awesome for dk especially with fair having the biggest delay out of all of his aerials. bair is good as soon as they near the edge but seriously people... try it and you will see that although it doesn't doo much knockback, it could be implemented into alot of combos.

I have alot of trouble hitting with this move, it's hitbox isn't so great.

This move iz effective i throw it in when fighting in the air.Most ppl expect fair so this catch's them of guard.
