Awakening Aether

Awakening Aether (, Awakening Heavens) is 's Final Smash in Super Smash Bros. Ultimate.

Overview
When this Final Smash is used, Chrom will dash forward while shouting "Anything can change!", "Now I'm mad!", or "Your end has come!" and strike forward with his sword, and any opponent that he hits with it will be stunned. If all of his opponents are hit, the camera angle changes to resemble that of attacks in Fire Emblem Awakening (unless he got the Final Smash by filling up his Final Smash Meter). Chrom then backflips away, then dashes forward while attacking the stunned opponents again with a more powerful strike, sending them flying.

Origin
Aether is a skill from the Fire Emblem series, originating in Path of Radiance as Ike's mastery skill. Chrom can learn the skill in Awakening as a Level 5. Lucina always begins with the skill as her inherited skill from Chrom, as well as or  if Chrom is their father (regardless of whether or not he has it equipped as a skill), and  if Lucina is her mother. In addition, certain versions of Chrom can learn it naturally in Fire Emblem Heroes, while others can learn it through skill inheritance.

In Awakening, Aether has a completely different animation unlike any of its other appearances, which this Final Smash is based on. However, it was never referred to as "Awakening Aether", which makes it likely that it was named this in Smash to not conflate it with Ike's Aether. All three of the lines Chrom can yell when activating this move are lines he says when performing a critical hit or activating an attacking skill (such as Aether) in Awakening. However, in Awakening, he said "Now I'm angry!" instead of "Now I'm mad!". Unlike Aether in the main series, Chrom does not recover damage or have any knockback multiplier on the attack, simply mimicking the attack animation.

Trivia

 * During his initial release trailer, Chrom's voiceline for calling out "Aether!" is said in a single phrase. However, the final release of the game has him split the word into two syllables, one from the initial flip backwards and the other for the actual attack, through adding a pause in the middle of the same voice clip. In the Japanese version, the voice clip had a pause in both the trailer and the final release, likely because the Japanese name for "Aether", "", has a pause in between its two syllables.
 * A similar issue was shown with Ike's Aether in Super Smash Bros. Brawl, where a cutscene from the Subspace Emissary used his Great Aether voice line, despite the scene showing him using his normal Aether.
 * During Awakening Aether, a special camera angle will activate during the second half of the attack, as a nod to the camera angles used in Awakening. However, if Chrom, or his opponent, are near a wall or a large part of the stage when Awakening Aether hits, the camera angle won't activate, and the standard camera angle will be in its place. It's possible that this was done to stop the in-game camera from clipping through the object(s), and obstructing the player's view.
 * This is the only Final Smash to belong to a variant of, but not be a variation of Critical Hit.
 * However, similar to Marth and Lucina’s Critical Hit, Awakening Aether involves Chrom dashing forward to strike.
