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: Eleven (from Dragon Quest XI: Echoes of an Elusive Age, commonly known as the Luminary), Arusu (from Dragon Quest III: The Seeds of Salvation, commonly known as Erdrick), Solo (from Dragon Quest IV: Chapters of the Chosen), and Eight (from Dragon Quest VIII: Journey of the Cursed King).

Super Smash Bros. Ultimate
During the E3 2019 Nintendo Direct on June 11, 2019 (PST), the heroes of Dragon Quest were announced as DLC fighters for Super Smash Bros. Ultimate, set to release during the summer of 2019 (PST) as the second fighter in the first Fighters Pass (as well as the third downloadable fighter overall), included within Challenger Pack 2. In a similar vein to Pokémon Trainer, Villager, Wii Fit Trainer, Robin, Olimar and Alph, Bowser Jr. and the Koopalings, Corrin, and Inkling, Eleven is the default skin for the character, while Arusu, Solo, and Eight can be chosen as alternative costumes. They all use a sword and shield, similar to Link, Young Link and Toon 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 (which fills up over time or attack to fills its). Slime also appear alongside them during taunts. With the notable exception of Command Selection, Hero's special moves switch between three types of magical attacks depending on the charge level and costs higher amount of MP when charged for longer, much like Robin's Thunder. Hero's down special move, Command Selection, instead has him choosing a variety of four randomly selected spells from a pop-up menu similar to the one from the original game. Regarding weight, Hero is one of the lighter heavyweights, being lighter than Mega Man but heavier than Mii Swordfighter and Cloud. Challenger Pack 2, including Hero, the Yggdrasil's Altar stage, and music from the Dragon Quest series, was released on July 30, 2019 (PST). Hero is classified as fighter #72.

Their magical skills can be selected from Command Selection are:
 * Sizz: Shoots a fireball directly ahead.
 * Sizzle: A stronger variant of Sizz.
 * Snooze: Fires a wave of energy that puts an opponent to sleep.
 * Bounce: Creates a reflect barrier around the Hero.
 * Kacrackle Slash: A physical attack that freezes opponents.
 * Kaclang: A move that encases the Hero in defensive metal, preventing knockback and grabs.
 * Zoom: A move that shoots the Hero into the air.
 * Kamikazee: Creates an explosion around the Hero, instantly defeating him, but causes large knockback and damage to opponents.
 * Psyche Up: A spell that increases the power of the Hero's next attack.
 * Flame Slash: A physical attack that deals flame damage to opponents.
 * Metal Slash: A physical attack that one-hit KOs metal opponents.
 * Heal: A spell that can heal the Hero.
 * Acceleratle: A spell that can increase the Hero's speed and jump.
 * Oomph: A spell that increases the Hero's attack power.
 * Bang: Fires a small explosive spell.
 * Kaboom: A stronger variant of Bang that fires a large explosive spell.
 * Whack: Fires a slow-moving dark purple projectile that instantly KOs opponents.
 * Thwack: A stronger variant of Whack that fires a large dark purple spark in front of the Hero that instantly KOs opponents.
 * Hatchet Man: The Hero unleashes a powerful downward slash.
 * Hocus Pocus: A spell that gives the Hero a random effect.
 * Magic Burst: The Hero unleashes a powerful, massive blast that grows in size.

Their Final Smash is Gigaslash that also involves the other 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 Eleven - attacks from behind, knocking away the puppet fighters from Link. Several gameplay clips of Eleven are shown: Eleven 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 Eleven. Arusu, Solo, and Eight join to assist Eleven, 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 Arusu using his Final Smash.

Classic Mode route
Aside from the final round, all matches in Hero's Classic Mode route are Stamina battles.

Palutena's Guidance
The following dialogue also applies to Joker, Banjo & Kazooie, and Terry. It was originally used for Mewtwo, Lucas, Roy, Ryu, Cloud, Corrin, and Bayonetta in Super Smash Bros. for Wii U, who are downloadable fighters in that game.
 * Pit: Who is THAT?
 * Palutena: I have no data on this fighter. I can't believe it!
 * Viridi: It must be an intruder from another dimension!
 * Pit: Whoever it is, the goal remains the same: to fight and win!

Trivia

 * Each of the heroes has a pallet swap that references another character or class from the series: Eleven's is based on Angelo, Arusu's is based on the hero of Dragon Quest V: Hand of the Heavenly Bride, Solo's is based on the hero of Dragon Quest, and Eight's is based on Terry from Dragon Quest VI: Realms of Revelation.
 * When playing on the Alefgard board in Fortune Street, Arusu is mentioned by various characters, who refer to him as "Erdrick" after the title awarded to him at the end of Dragon Quest III.
 * The Hero is the first and currently only third-party character to have other characters from the same series as alternate costumes in the Super Smash Bros. series.
