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.

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 Fighters Pass fighter (as well as the third downloadable fighter overall), included within Challenger Pack 2. 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. 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 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.
