Executed by performing two quarter-circle forward motions and pressing punch, Q performs a combo of two strikes, a gut punch and then a two-hand hammerstrike. However, these two strikes are monstrously powerful, and either one will send the opponent flying.
The hammerstrike hits the opponent so hard that they bounce off the ground and high into the air, providing an opportunity for juggling. If for some reason the combo is interrupted after the gut punch (e.g. the opponent hits Q just as the gut punch lands), the opponent will still be hit in most cases, and sent flying to the other side of the screen.
The attack has a very high priority and can be used to trump most other attacks, including other Super Arts (as demonstrated below). It can also be canceled into after any successful Dashing Straight, even ones on airborne opponents.
