There are a few unreleased heroes that have been found within the game files. Some of them have all of their skills and SI items, while others only have a story.
Keep in mind that the unconfirmed heroes might not ever be released or could be completely redesigned in the future.
Dimensional Hero – Prince of Persia
Prince of Persia artwork was published by an artist that has made hero art for AFK Arena in the past.
Also, a quote describing a hero was found in the game files by Hashimaru.
“A warrior hero in the Hollow Visitors. Able to use Sands of Time to make time go backwards to avoid death.”
“Prince of Persia: The Sands of Time” was the name of the first Prince of Persia game developed by Ubisoft when they bought the rights to the franchise. It was also a movie.
The speculation is that the Prince of Persia will be a new hero in AFK Arena. Lilith have already collaborated with Ubisoft in the past for Assassin’s Creed.
