Ben 10: Negative RisingEdit

Season OneEdit

Video GamesEdit


  • He is from Dimension 666, due to the evil characteristics often associated with the number 666.
  • Due to the death of his grandfather, he has a very...enraged personality, blaming himself for Max's demise to the point that he has become a ruthless vigilante, straying away from the path of a hero.
  • His enemies were...a bit tougher to defeat than his mainstream counterpart's enemies, putting aside techniques and personalities.
  • He, like Albedo, will have a special dedicated to him.
    • Said special will be called The End of a Hero.
  • He hates smoothies, similar to how mainstream Ben disliked smoothies at age 11.
