Up aerial

An up aerial, also known as an up air and commonly abbreviated as a u-air, is an aerial attack in Super Smash Flash 2 or Fraymakers that is performed by pressing the up and attack inputs in conjunction while in midair. It can also be performed in SSF2 by pressing up with the "C-Stick" controls in midair or in Fraymakers by pressing up with the "secondary stick" controls in midair when assigned to tilt attacks or strong attacks.

Up aerials typically hit directly above the character or in an arc over them. They often have large range and low knockback and are useful for coverage, anti-air tools, and starting combos, particularly juggling and ladder combos that chain multiple up aerials together.

In SSF2, attempting to up aerial while holding a throwing item throws it upward.
