Owain

How Owain joined the Tourney
When Owain first runs into Lissa, he introduces himself as her son from the future and proves his royal heritage with the Brand of the Exalt on his arm. He brings theatrics to battle, referring to his weapons with names he's given them and shouting the names of his special moves as he performs them.

When highlighted
Owain hides his face with his right hand.

After the announcer calls his name
Owain says "I've seen the future..." jumps high and lands close to the camera and covers his mouth continuing "and you didn't make the cut!"

Blazing Blade of Doom (Neutral)
Owain swings his sword sending a wave of fire forward.

Sacred Stone of Strike (Side)
Owain thrusts his sword sending blue flames forward.

Steel of the Radiant Dawn (Up)
Owain jumps high glowing his sword with light and slams it.

Demon Hunting Blast (Down)
Owain stabs forward in a sliding thrust, then via the second input slashes outward in a step and points his sword forward to fire three dark cutting waves in a spread.

Abysmal Body Blow (Hyper Smash)
Owain announces his attack's name, clutches his left hand glowing with darkness and thrusts it forward, but then says "Restrain yourself, sword hand!" and slashes his sword right giving hard damage.

Quenchable Blood Blades~Sword of the Knight Errant and Obsidian Sword of the Blade Knight (Final Smash)
Owain charges up and summons a large white sword in his right hand saying "Sword of the Knight Errant...", and a large dark sword in his left hand with "and Obsidian Sword of the BLACK KNIGHT!". He then does a jumping slash hitting two times, then a downward slash, then two slashes in front, then announces "Darkness awakens!" and finishes by doing a spreading slash.

Bonus Costume
Owain holds possession of one Bonus Costume, that being is Odin appearance from Fire Emblem Fates. To unlock, one must clear Classic-Adventure with Owain without continuing. After Queen Nehelenia (or Super Queen Nehelenia)'s writhing in agony before exploding, the announcer will say "You've earned a new costume!" and a Smash Ball (appears on the lower-right corner) will appear with a message saying "Outstanding! You got Owain's Odin appearance! Leo would be proud!" Then, highlight Owain and press Minus.
