The Corrin amiibo functions in Super Smash Bros Wii U/3DS exactly like every other amiibo for the game: allowing you to train a CPU up to level 50 that you can battle against or alongside whenever you wish, as it learns how to become a better fighter. Additionally, Corrin is compatible with Fire Emblem Echoes: Shadows of Valentia, the latest game in the Fire Emblem series, and will most likely be compatible with Fire Emblem Warriors as well. The amiibo itself looks great. The paint on mine was flawless and the everything was in its proper place. I've seen complaints about Corrin coming with a bent sword but mine was fine. If yours is bent though, you can simply use some heat to bend it back into place (assuming you open and use your amiibo). Overall this Corrin amiibo is an excellent purchase for any Fire Emblem fan, given its compatability with Super Smash Bros, a current Fire Emblem game, and at least one upcoming game as well.
