After a week of rumors and speculation, Nintendo has officially dropped Super Smash Bros. Ultimate version 4.0, which includes the new Dragon Quest Hero fighter and a few other key additions. The update was accompanied by a full 20-minute-plus Nintendo Direct, which you can scope out below.

As you can see, Hero is actually several heroes in one, featuring skins of the protagonists from Dragon Quest III, Dragon Quest IV, Dragon Quest XIII, and Dragon Quest XI. The Hero can command a large variety of different spells from the Dragon Quest series, with his down special bringing up a Command Selection menu filled with randomized spells. Overall, it looks like Hero will be a fairly complex character to use.
