Additional Stat Boosts: More Skill Power, More Max HP, More Reality for Sven
- Kristoff & Sven are the 100th Hero added to the game. Because of this, Disney Heroes had a special event in which all players received 10 Kristoff & Sven Chips for free every day for eight days for a total of 80 chips, enough to evolve Kristoff & Sven to three stars.
- Despite their name implying that they always attack as a team (like with Sulley & Boo or Timon & Pumbaa, among others), Kristoff & Sven's dynamic during battle is much more similar to the dynamic between Jasmine and her pet tiger, Rajah, who acts as an assistant to her when she summons him in battle.
