Today, Ike has been announced as a playable character for the upcoming Super Smash Bros. game. Officially confirmed in Miiverse and the Super Smash Bros. website, Sakura also gave some comments:
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.
