Torrential Roar

Torrential Roar (, Raging Stream Roar) is Corrin's Final Smash.

Overview
Corrin partially transforms into dragon form, punching one fist down and causing two yellow geysers of light to erupt on both sides. In terms of the quote used during it, Male Corrin says "Out of the way!" (, Stand out of my way!) while female Corrin will say "This ends here!" (, This is over!).

Any opponents hit by the attack will get transported to a mountain-filled area, where Corrin, in full dragon form, then fires a large whirlpool to drown anybody caught in it away and cause them to suffer massive knockback when the attack is over.

The Final Smash deals a total of 40% damage — 5% from the initial shockwave, and 35% from the resultant whirlpool.

Origin
Similarly to Ike's Great Aether, this move is unique to the  series, never making any appearance in Fire Emblem. However, this move may hold some inspiration from, the deuteragonist of , who has the ability to use hydrokinesis to great lengths with the power of her necklace. This ability is notable in a cutscene from both the Birthright and Conquest paths, where she used her water manipulation skills to exorcise the evil force controlling King Garon. It may also be related to their home game's main antagonist, ' ability to manipulate water, which apparently Corrin also possesses, as in their dragon form, water flows from their feet during the cinematic battle of Fire Emblem: Fates.

The English version of  would later name one of Female Corrin's skills after the Final Smash. However, similar to the Dancing Blade in Fates, the skill was not originally a reference. In the original Japanese version, the skill is instead called 竜穿砲 (Dragon Fang Cannon), and visually instead features Corrin's Dragon Fang Shot.
