Heroes are a tower category in Bloons TD 6 and Bloons TD Battles 2. They are one-off towers with unique (and often complex) mechanics. Unlike other towers, the player is only allowed to choose one Hero to use in a game, and only one of that Hero can be placed per game. Rather than having upgrades, Heroes gain XP at the end of each round and level up upon reaching certain thresholds, increasing their strength and/or unlocking new Activated Abilities.

Experience

"Hero XP" redirects here. For the Hero equivalent of Tower XP in Bloons TD Battles 2, see Hero Point.

Heroes gain XP at the end of each round. The amount depends on the round, with higher-numbered rounds giving more XP. Most levels take more XP than the previous level, though in BTD6, levels 12, 14, and 19 take less XP than the previous level, and level 20 takes less XP than level 18. Since the amount of XP earned per round and amount of XP it takes to level up both increase over time, the number of rounds it takes for a Hero to level up stays roughly the same throughout the game if placed on the first round. If placed later in the game, Heroes will initially level up faster than normal due to the rounds giving more XP relative to their level, but it normalizes as the level approaches the usual value. At any point, the next level can be unlocked instantly by spending cash, at a rate of $1 per 1 XP.

In BTD6, the amount of Hero XP earned at the end of each round is the same as player XP and tower XP outside of freeplay and Knowledge modifiers. Like player and tower XP, Heroes gain more XP and level up faster on higher map difficulties; 1.1× faster on Intermediate, 1.2× on Advanced, and 1.3× on Expert. If multiple Heroes are in play (via Co-op or the Bloons TD 6 Birthday Party quest), the XP earned on each round is divided evenly among each Hero.

XP curves

All Heroes have an "XP curve" that affects how much XP each level requires. Each level's XP requirement is multiplied by the curve (rounded half up), so a higher multiplier means the Hero takes more XP to level up.

In Battles 2, all Hero Alts have the same XP curve as the Heroes they are derived from.

Activated Abilities

Most Heroes have at least two Activated Abilities: one unlocked at level 3 and one unlocked at level 10. Some Heroes have a third ability unlocked at level 7. In general, the level 3 ability is weaker and has a shorter cooldown, the level 10 ability is stronger and has a longer cooldown, and the level 7 ability is situational. All Heroes' level 10 abilities are enhanced at level 20. Geraldo is the only Hero to lack any abilities.
