The series is also represented in the 2018 crossover fighting game "Super Smash Bros. Ultimate" via downloadable content released in July 2019. Unlike most of the game's roster, the "Hero" is not a single playable character but rather a character slot shared by four separate, albeit functionally identical, main protagonists from the series: Eleven (also known as The Luminary) from "Dragon Quest XI", Arusu (also known as Erdrick) from "Dragon Quest III", Solo from "Dragon Quest IV", and Eight from "Dragon Quest VIII". Other elements from the series are also featured, such as Slimes and a stage based on Yggdrasil's Altar from "Dragon Quest XI".
