If you hit someone in the air as an anti-air, you can free cancel it into the regular super.
You can also do a 2 meter, 1 drive combo by doing j.C, st.C, f+B, hcb,f+P, qcf+AC, qcfx2+P for a 500 dmg combo.
Other than that, if you do it as a knee jerk wake up reversal or as an anti-fireball measure, you can only free cancel into the EX Super. If you placed your character in front of the opponent and hopped backwards, that would be the distance where this no longer works for free. It only works from that distance to right in their face.
