Kazuya (SSBU)/Neutral aerial
Kazuya throws a diagonally downward jab, similarly to Ryu, Ken, and Terry's down aerials. It is the only neutral aerial in the game with the ability to conventionally meteor smash, although it is moderately weak; however, it is very quick to interrupt and has good startup for a spike, which makes it extremely versatile as a combo starter, both when landing or rising with the move. It also serves as an effective gimping tool. The sweetspot uniquely has altered knockback on grounded opponents to where the meteor smash puts them into tumble at any percentage, although on aerial opponents it is a lot weaker, only starting to do so at around 90%. The move is based on the universal jumping left punch from Tekken.
Ferps tech is an advanced technique exclusive to Kazuya in Ultimate. The technique was popularized by professional Kazuya player Ferps, of which the technique is named after. The technique involves performing a turn around neutral aerial while landing on a platform. If done correctly, Kazuya will land on said platform significantly quicker than other methods like an airdodge, allowing for expanded movement options and more lenient combo extension windows.
