f22 is a pretty good anti air with good range, hitbox and priority. Also leads to great damage. However, it’s not as consistent as s1. Standing 1 has an amazing hitbox from every range. It even can anti air cross up attempts.
Her df1 can anti air but has way more startup.
A surprising anti air in 1st Round KO is clinch (df3). It has a bigger hitbox than you think and than it looks. It straight up can snatch the opponent out of the air at the right ranges and timing.
