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 generate additional income from Bloons or to support nearby monkeys, allowing them 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 the potions can be lobbed over obstacles, the tower is able to ignore Line of Sight, and it is currently one of five non-moving towers to do so, the others being Spike Factory, Mortar Monkey, Super Monkey (Sun Temples and above), and Wizard Monkey (Guided Magic and above).

The Alchemist, like most other towers, has the appearance of a monkey, despite not having "Monkey" in the name. It wears a purple buttonless overcoat with a yellow rim and with its sleeves rolled up. It also has a pair of goggles with pink-tinted lenses and gold frames, attached by a brown strap. Strangely, the goggles are never worn directly over the Alchemist's eyes except for the Bloon Master Alchemist (x/x/5) and Unstable Concoction (x/3/x). It carries a round-bottom flask filled with red acid. In the artwork, the flask does not appear to be capped.

  • 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 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.
