... It spikes? Never seen it do anythin' 'sides diagonal-upwards knockback.
Ganon's Up-Tilt can knock someone off a ledge, but not spike.
The opponent gets knocked diagonally-downwards on low percentages, and diagonally upwards on high percentages. They can still recover quite easily.
Demo 2.6 removed Ness's Easter Egg. ;__;
And Charizard's Side-Taunt is different, I think. I don't remember if that was the same in 2.5b.
Toon Link's Bombs (Down-B) now deal two consecutive hits upon impact. Makes them a lot stronger, but more risky.
His Down-Taunt now heals only 2%, 1% on each gulp. It got lower, from what I remember.
I think Sonic's F-Air lost some power too.
