Hero

The Hero is the main playable character of the Dragon Quest series. The appearance, skills, and role of the hero varies between the games. Four of these heroes appear in Super Smash Bros. Ultimate: the Luminary (from Dragon Quest XI), the Legendary Hero (from Dragon Quest III, commonly called by his title of Erdrick), Hero of Zenithia (from Dragon Quest IV, commonly known as Solo), and the hero of Dragon Quest VIII.

Super Smash Bros. Ultimate
During E3 2019 on June 11, 2019, the heroes of Dragon Quest were announced as DLC fighters for Super Smash Bros. Ultimate, released during the summer of 2019. The Luminary is the default skin for the character, while the Legendary Hero, Zenithian Hero, and the hero of Dragon Quest VIII can be chosen as alternative skins. They all use a sword and shield, similar to Link, and have access to magical abilities from their series, such as Sizzle. Many of their basic attacks use sword jabs and swings, with their shield able to block projectile attacks. Their magical attacks are limited by their MP gauge. Slimes also appear alongside them during taunts.

Their known magical skills are:
 * Sizzle: Shoots a fireball directly ahead.
 * Kasizzle: A stronger variant of Sizzle.
 * Snooze: Fires a wave of energy that can put an opponent to sleep.
 * Bounce: Creates a reflect barrier around the hero.
 * Kacrackle Slash: A physical attack that can freeze opponents.
 * Kaclang: A move that encases the hero in defensive metal, preventing knockback.
 * Zoom: A move that shoots the hero into the air.
 * Kamikazee: Creates an explosion around the hero, instantly defeating them, but causes large knockback and damage to opponents.
 * Psyche Up: A move that raises the hero's tension.

Their Final Smash also involves the other playable heroes from the mainline Dragon Quest that are not playable. In Hero's reveal trailer, Link is shown dueling puppet fighters of Marth and Meta Knight, both of whom were created by Dharkon. Link is overpowered by both puppet fighters, who prepare to rush him for a final hit. However, throughout their battle, a horse is galloping towards Link and the puppet fighters. When the Marth and Meta Knight puppet fighters are about to attack Link one more time, the Hero - revealed to be the Luminary - attacks from behind, knocking away the puppet fighters from Link. Several gameplay clips of the Luminary are shown: the Luminary is KOing opponents at first, but is later KO'd himself several times. The gameplay cuts back to CGI, showing Dharkon's puppet fighter army cornering a weakened Luminary. The Legendary Hero, the Zenithian Hero, and the hero of Dragon Quest VIII join to assist the Luminary, where all four Heroes rush towards the puppet fighter army. Gameplay footage of all four Heroes is shown, where they all work together to KO their opponents. The Hero's trailer ends with the Luminary using his Final Smash.

Trivia

 * When playing on the Alefgard board in Fortune Street, the Legendary Hero is mentioned by name by various characters, who refer to him as "Erdrick" after the title awarded to him at the end of Dragon Quest III.
