Combatants' Home Productions

Like with series, sometimes the companies deserve credit too, including the productions that most of the Death Battle combatants are from (with the exceptions of Justin Bieber, Rebecca Black and Chuck Norris because they are real life people), and here they are in Death Battle Episode order:
