Characters

Character, also referred to as Heroes are the ensemble of main towers in Bloons Adventure Time TD made up of personified takes on Bloons TD series towers and characters from theAdventure Time series.

Narrative
Unlike Bloons TD games before it, Bloons Adventure Time TD has a loose story which revolves around the arrival of the Bloons into the land of Ooo, which is told through dialogue between the Characters before a new Adventure begins and after one ends with the collection of a new Character.

Most Adventures which feature a new character often have one of these sequences, though alternate variants of older Characters lack this kind of interaction. There are also some Adventures which are purely for the loot at the end, playing much more as non-sequitur storylines starting and ending with the brief description given to them at the opening of their Adventure.

Gameplay
To differ itself from the typical formula of Bloons TD further, each Character can only be placed down once in a game, preventing purchase of a second of that same character type until the first character is sold. In a sense, this mechanic is highly reminiscent of Bloons Monkey City and its own limited brigade of towers to utilize per map.

Unlike BMC however, there is no method to increasing the quantity of any Character outside of rare abilities such as Finn using the Finn Sword Activated Ability. In place of having limited towers of each type is the presence of Allies, a new mechanic which lets a Character bring along another tower to the fray, up to four per character can be introduced in this way, with some being able to be placed multiple times.

Trinkets are also a highly variable factor for towers, allowing for stat boosts to radical abilities which will let the player's towers perform overall better than before.

Both Trinkets and Allies depend on the Character's current Level, which can be increased with Star Level Currency collected along one's adventures through levels.
