Combatants' Home Series

Most of the Death Battle combatants are taken from their own home series to be pitted against other combatants (The only exceptions however who are not listed are Justin Bieber, Rebecca Black and Chuck Norris because they are real life people, Segata Sanshiro because he is from advertisements and Smokey Bear and McGruff the Crime Dog because they are from PSA's), They are listed by the following series in Death Battle episode order.

Note: Bold characters are victors and didn't die, Italic characters means they've fought more than once, characters with '*' symbols next to their name have won or survived more than once and characters with two '*' symbols means they have undecided fates (their battle has not been released yet).
