A midair command normal where Frank drops straight down in a damaging speed on his knee, which hits overhead.
Taken straight from Dead Rising. This is normally used to end combos and position yourself right next to your opponent to setup for OTG scenarios such as going right into a Snapshot.
However, it can also be used to instead land back on the ground quickly into a cancel to any other move other than the aforementioned Snapshot to quickly regain neutral ground, or to land a Snapshot OTG through other means if the Knee Drop itself whiffed during specific types of air combos/aerial raves that do not involve his j.S or Knee Drop used as the finishers.
