Editing Aether

'''Aether''' ({{ja|天空|Tenkū}}, ''[[wikipedia:Five elements (Japanese philosophy)#Void (Aether)|Sky]]'' or ''Aether''), is the [[up special move]] of [[Ike]].

In ''Super Smash Bros. Ultimate'', the thrown sword no longer clips through the stage and instead follows the stage's contours, which hinders the move's safety while recovering. However, the super armor on startup is now significantly longer and starts at frame 5, which gives him a decent [[out of shield]] option. As meteor smashes now KO opponents once they are offscreen, the downward slash is also more effective for [[sacrificial KO]]s. Following update 8.0.0, the landing hit launches at a lower angle with significantly increased knockback scaling, which vastly improves its KO ability. These changes render the move capable of reliably KOing middleweights around 115% from center stage and around 70% near the ledge, if all hits connect. Aether's drastically improved KO potential has also granted Ike a new kill confirm from his neutral aerial, albeit only at mid percents when near the ledge.

In ''Ultimate'', a similar glitch occurs if Aether hits {{SSBU|Little Mac}}'s [[Slip Counter]] while the [[gameplay speed]] is modified. Ike's sword will be slowed down, but Ike's animation will not be. If used on the ground, he will enter the phase of his animation where he leaps up to grab the sword (assuming the counter doesn't hit him, such as if he is [[Invincibility|invincible]]), but will not actually move upwards, and will then continue performing the animation on the ground without the sword, with the sword then snapping to his hands when it reaches the end of its animation, just before the descending portion of the move. If used in the air, Ike will jump upward, but the sword will still be slowed down, and won't snap to his hands until its animation is finished.

Aether is a powerful [[fireemblemwiki:Skills|skill]] available to Ike upon promotion in ''{{iw|fireemblemwiki|Fire Emblem: Path of Radiance}}'' and ''[[fireemblemwiki:Fire Emblem: Radiant Dawn|Radiant Dawn]]'', and later to [[Chrom]] and [[Lucina]] (or any of Chrom's other female children) in ''[[fireemblemwiki:Fire Emblem: Awakening|Awakening]]''. Aether is strikingly similar to the generic mercenary's critical hit animation from the ''Game Boy Advance'' Fire Emblem titles, and because Ike is a mercenary, this can be considered a reference. When activated, the skill deals two strikes to an enemy, combining the effects of the skills {{iw|fireemblemwiki|Sol|skill}} and {{iw|fireemblemwiki|Luna|skill}}. When Ike uses Aether in ''Radiant Dawn'', he throws his sword upward, jumps, catches it, then comes down with a spinning cut that heals Ike equal to the [[damage]] inflicted (the effect of Sol), followed by a second rising strike that is performed as Ike puts space between himself and his opponent, which treats the foe's Defense as if it was halved or 0 (the effect of Luna in ''Path of Radiance'' and ''Radiant Dawn'' respectively). However, neither effect is applied to Aether in ''Smash'', and only the Sol portion of Aether's animation is incorporated. Its animation was changed in ''Awakening'', which went on to become the basis for [[Awakening Aether|Chrom's Final Smash]] in ''Ultimate'', though said animation has not been seen since.

''{{iw|fireemblemwiki|Fire Emblem Heroes}}'' introduced many upgraded versions of Aether for Ike, such as Mayhem Aether for his "Fallen" version and "Radiant Aether" for his "Legendary" version, the latter of which has a somewhat similar animation to [[Great Aether]]. Aether skills in ''Heroes'' generally act the same as in other Fire Emblem titles, although they are inheritable to other units. Variations, however, are normally non-inheritable, and so far have only been featured on alternate iterations of Ike.

*In {{for3ds}}, the first use of Aether after using [[Great Aether]] will not have sword trails.
