air up square, (land then jump again), air square square, air square square, up triangle
not sure if it's been posted before. It doesn't work on small characters, and it's tricky to land the first hit, but it's still probably more practical than every other wall-less AP burst I've seen.
it's still not very useful though :( it's hard to land the first hit on anyone not called Sweet Tooth, Big Daddy or Zeus (to hit normal human size characters you practically have to land into them as you use the move).
air up square just before you land confirms into Radec's lvl1 too. I think giving Radec's air and ground up square a better hitbox (so it hits in front of Radec & hits small characters) would be a good buff, if only because it'd actually give his up square more use & make this combo/his HC more practical.. --- PSASBR: Toro, Fat Princess
