Editing Dragon Quest: The Mark of Erdrick (section)

===In Videogames===
''The Mark of Erdrick'' has had a handful collaborations with the Japanese version of {{DQStars}}. The collaboration include a multitude of cosmetic equipment based on characters like Arus, Kira, Yao, Kadal, Jagan and more; Fiend-difficulty boss fights against multiple villains from the series like Orochi or Imajin, and stamps for multiplayer communication. Kamui Fujiwara designed new armor for the collaboration event.

It also collaborated with {{Keshi Keshi}}, with erasers based on Arus, Kira, Yao, Porog (both [[gadabout]] and [[sage]] forms), Jagan and Gunon. Players would get Poron by just playing the game while the event lasted, with the item to upgrade him to sage being available as a quest reward. Arus, Kira and Yao were gacha erasers. The erasers of Jagan and Gunon were unlockable by progressing in the event.

The members of Arus's party also delved into the world of Final Fantasy Brave Exvius, with Arus, Yao and Poron being added into the game as gacha units, Killa as a free unit, and Gunon and Jagan as bosses. Aside from the units themselves, a couple Vision Cards based on them were also available.
