This is like most AYD but in this one, you only have 1 HP! so get creative but don't be too OP! and aggression level exists, just check the notes of credits of remix 0 to understand Rules 1. You're allowed to add music 2. no op character 3. You can add enemies because not being able to do so would eventually make defenders too op 4. You don't have to add your character to the thumbnail 5. No changing existing characters 6. Max damage from a character is 5 7. No copying other defenders *May add more rules*
