Here's a list of the heroes to kill some heroes during the war:
- President (slain by the Chritchellites (Samurai Jack).)
- The Chief from the Man called Flintstone (brutally torn apart by Tyler with a buzzer)
- Stacy from Total Drama (shot by Tyler in the middle of a battle interrupting the fight to talk about objects created by her ancestors)
- Nicodemus (Slain by Katz through a poisonous spider)
- Eva (Accidentally slain by whatever hero you pick to be controller by the One Ring)
- Necron 99/Peace and Justin (Killed by Aresia)
- Odette (would pass away after an attempt to save whoever you pick from monsters or dinosaurs during the final stages of the war similar to Meg in HvVW and her soul would end in Tartarus)
- Ezekiel and The Prince (Happily Ever After) (after being freed from Mok's control, Ezekiel sides with the heroes and battles whoever you pick and gets aided by the Prince. However at the final battle's half after the Legion of Darkness appears, they both sacrifice their lives to kill such villain. The Prince's soul will end in Tartarus alongside Odette)
- Duncan (Fell from a cliff to a fiery demise after trying to save the heroes from the portal. His soul will end in Tartarus alongside the souls of the Prince and Odette)
- Joseph Korso (Died just like in the same way he does in Heroes vs Villains)
