Soaring Slash

Soaring Slash is Chrom's Up Special. Chrom swings his sword overhead and then leaps upwards into the air; he then performs several flips, swinging his sword around him, and then does a descending strike. The descending strike will spike opponents caught in it.

Origin
The Soaring Slash originates from a similar maneuver performed by Chrom in several cutscenes during Fire Emblem: Awakening, namely the scene where he fights Marth in Arena Ferox.

Trivia

 * The move bears a resemblance to Aether, Ike's Up Special; however, unlike Ike, Chrom does not throw his sword before performing the maneuver.
