Heroes are a special type of tower that were introduced with Bloons TD 6. Heroes are unique characters that have their own personality, voice lines, abilities and attacks. The major difference from regular towers is that only one Hero may be equipped and placed per player per game. In addition, Heroes do not have the conventional upgrade system. Rather, they have a single upgrade path, with individual tiers being split into smaller "levels" that level based on Hero XP (distinct from Tower and Rank XP), which is accumulated automatically as rounds progress. In co-op each player may have one Hero, so XP is split evenly among players.
Unlike normal towers, only one hero can be placed on the track for each game and automatically gains XP needed to upgrade itself, making them more useful the earlier they are placed. XP gain can be increased or decreased by outside factors, such as Energizer or Monkey Knowledge.
However, they can also be upgraded instantly for a sum of in-game cash. The more XP a hero already has, the lower the amount of cash required to upgrade the hero to the next level. Spending money to level your hero also increases sell price.
Each hero has multiple abilities (all have two with the exception of Striker Jones, Ezili, Adora, Corvus, and Admiral Brickell, who have three and Geraldo who has one) that can be used to the player's advantage. The first ability is unlocked at level 3, and the second ability is unlocked at level 10; for Jones, Ezili, Adora, Corvus, and Brickell, they gain their second ability at level 7 and third at level 10. The highest level a hero can reach is 20. An exception is Geraldo, who has an "ability" in the form of Geraldo's Shop, unlocked at level 1.
Hero Leveling[]
Heroes require a set amount of XP per level (see BTD6 Heroes XP). For most purposes, the amount of money needed for an upgrade is the amount of XP required. Heroes gain XP at the end of the round by the same formula as towers (see BTD6 Towers XP).
All heroes have a specific XP ratio. Heroes with a higher XP ratio require more XP to level up and therefore level up slower.
As maps usually do for player and tower XP, they increase the XP earned for heroes by 10% for each track difficulty above beginner (10% for Intermediate, 20% for Advanced and 30% for Expert).
The following tables show the round on which a Hero will reach Level 20, if placed on round 1, and if no levels are bought.

The Heroes[]
There are currently 16 heroes in BTD6, with new ones occasionally being added in new updates.
For Monkey Money (usually 2500), the player can buy skins to change the voice of the hero and the appearance of the hero and its attacks. These are purely cosmetics and grant no in-game advantages. These are the skins currently in the game:

Trivia[]
Gwendolin, Quincy (in his Cyber Quincy skin), Ezili, Pat Fusty, Etienne, and Corvus are the only heroes that call out a B.A.D. by its name.
Among all the heroes that call out a M.O.A.B. by its name, Striker Jones, Etienne and Lifeguard Brickell say 'M-O-A-B', while all other heroes pronounce MOAB as 'Mow-AHB'.
Heroes say different voice lines when wearing an alternate skin.
Pat Fusty has the shortest range of all of the heroes.
Adora has the longest displayed range of any hero when her Long Arm of Light ability is active.
You can annoy Heroes by tapping (or clicking on) them 12 times.
In Version 35 and before, there were two counters for this, alternated between Level parities, with neither counter getting reduced except with a reset for the given counter after the thirteenth tap/click for the second annoyance quote. When the counters had been given a naturally occuring reduction and how that works has not been documented.
You can replay hero placement voice lines by using the Support Chinook moving ability on them.
To unlock every hero as of Version 40.0, it will cost a total of 48,500. An additional 62,500 is needed to unlock every cosmetic skin, for a combined total of 111,000.
