Starting in Season 10, there is at least one winning matchup that was added as a result of winning a fan poll exclusive to those with DEATH BATTLE membership. The polls for Season 10 was done for two matchups - one done in 2D animation and one done in 3D. The polling for Season 11 was changed to a tournament bracket with the winning matchup being the sole episode guaranteed for the season. The winners of the Season 10 poll were Bill Cipher VS Discord for 2D and Cole MacGrath VS Alex Mercer for 3D, both of which being among the most highly requested matchups in the show's history.
Several content creators have voiced their approval/disapproval for some episodes.
In the earlier seasons, many fans disliked the show's habit of revealing only one combatant while withholding their opponent's identity to plug their social media instead. After showing Green Arrow would appear next, Chad shows Hawkeye as his opponent, clearly aware of their obvious choice. They also revealed Charizard's fight against Agumon after that fight, along with a hype-inducing video package with both of them in top form. As the last such preview was when Iron Man fought Lex Luthor, it was a welcome surprise. The show took a hiatus from doing that until Meta and Carolina's fight revealed the match between Cammy and Sonya with an additional preview of the animation. Starting with Natsu's fight with Ace in Season 4, showing both fighters has become standard.
