Ike from the Fire Emblem Series Confirmed for Super Smash Bros. 4

Sakurai: Pic of the day. Ike, the swordsman of magnificent strength, joins the battle!! Strike your foes down with his powerful smash attacks.

For this game, Ike's design is based on the hero that appears in Fire Emblem: Radiant Dawn. His sword deals heavy damage in Smash Bros., so this design suits him very well! Rest assured, he can use Aether as well.
