Flight, or Hikou (飛行, Aviation) in Japanese, is a mechanic that allows characters to fly for a period of time, normally 2 seconds. In X-Men: Children of the Atom, it was an X Ability move that cost meter. In later games, this move is commonly shared by a variety of characters.

Despite its input ending in two attack buttons at once, it is treated as a normal special move and not a Hyper Combo. The characters that can use this are stated below.
