The card artwork depicts an Armor Powered Bloon radiating hot gas towards several Lead Bloons, the gas caulking the gaps between the metal plates on their exteriors.
To maximize its potential, always use an Armor-focused deck. Lead Coating Bloon and Mass Lead Production are among the best ways to maximize Armor before playing this Bloon.
Even with a decent amount of Armor on the friendly field with slow Large Bloons, two Lead Coating Bloons, and a Mass Lead Production, Armor Powered Bloon can gain a decent amount for 5 Gold and 3 delay; for instance, three undestroyed candidates with 25 Armor gives +375 HP.
If maximized well, an Armor Powered Bloon can gain thousands of HP.
Similar to Draining Bloon, duplicating an Armor Powered Bloon via Double Trouble allows its copies to keep stacking HP.
