A/N: Here are some Death Battle tier lists I made. So here they are

Notes: "The One" means the best opponent and the number one option, "Good Alts" means the second best option and perfect alternative, "Fine" meaning meh or it could work and wouldn't mind it happening, "Eh" means it's bad option and "No Thanks" meaning Hell no, the matchup is terrible, and should NEVER happen.
