Like the Dragon Quest series, Hero has an MP meter that can drain when using moves, the Hero’s down special actually brings up a menu of moves that Hero can use their MP on.
In a “small budget” video on the Nintendo YouTube channel, game director Masahiro Sakurai showcased the newest DLC fighter for the game Super Smash Bros. Ultimate, the various forms of the Hero from the Dragon Quest series.
Sakurai discussed that this is the first time the Dragon Quest heroes have been able to fight each other, and that the voice actor for the Hero from Dragon Quest 8, Yuki Kaji, has expressed that it was a dream of his to have his voice in the Super Smash Bros. series.
