Alchemist

“	Harnessing powers of science and magic, splashes Bloons with acid, also brews various potions with different effects.	”
	^{~ Bloons Tower Defense 6 description}

The Alchemist is a tower that first appeared in Bloons TD 6. It throws potions that slowly deal damage to bloons over time, similar to Corrosive Glue, just without the slow effect. It cannot detect Camo Bloons without aid from other towers. The Alchemist can be upgraded to aid in earning money and to aid other monkeys, such as potions that allow monkeys nearby to pop Lead Bloons and do extra damage to M.O.A.B. Class Bloons. The Alchemist by itself is relatively weak and generally relies on other monkeys to truly utilize its power. Note that he can reapply his acid, refreshing the damage amount. Due to the fact that he lobs his potions, he ignores Line of Sight and 3D objects, and is currently one of four non-moving towers that do so, the others being Spike Factory, Mortar Monkey, Super Monkey (Sun Temples and above) and Monkey Apprentice (with Guided Magic).

Alchemist, like other towers, has the appearance of a monkey, despite not having monkey in the name. It is wearing a purple overcoat with yellow rim, no buttons and rolled sleeves. It also has a pair of pinkish goggles with golden frames and rubber bands to wear it. Strangely, this tower never wears it's goggles except Bloon Master Alchemist (x/x/5). It uses a flask filled with red acid to lob at bloons. In the artwork, the bottle doesn't have a cap on it.

Trivia

The Lead to Gold upgrade may be a reference to an old medieval myth where court alchemists were trying to find a way to turn base metals into gold.
The Rubber to Gold upgrade can turn Ceramic Bloons into Gold, which should technically be impossible since they are made of clay, not rubber.
- However, the description says all "bloons", and the Ceramic is a bloon.
The Transforming Tonic upgrade may be a reference to Pop Fizz from Skylanders, as he drinks a potion that makes him turn into a large, monstrous creature, with a similar design and colour scheme.
The Alchemist is one of four towers whose name consists of only one word, the others being Druid, Bloonchipper, and COBRA.
- In BTD2, the Boomerang Monkey was called Boomerang.
Although ice and glue can be removed by tornadoes, the potions from Alchemist cannot.
