Battle Seasons

Battle Seasons are seasons in Bloons TD Battles 2. They take role in determining how long a "tournament" season must last for. Medals and season-specific cosmetics are affected by this. After each season, the player wins a new medal based on their highest arena reached and their current trophy count is halved (rounded down if necessary). Their initial Battle Arena placement in the new season corresponds to that new trophy count.

Medals are earned after each battle season. They represent the placement at the time of the end of each season, as well as the season number determined by Roman numerals (e.g. I, II, III, IV, etc.).
