Prince of Darkness is a MagicMonkeycard in Bloons Card Storm. Instead of attacking, it summons a Zombie MOAB when placed (without generating Bloontonium) and restores up to 50 health for all Bloons on the player's side at the start of each turn. Only one Prince of Darkness can be in the Collection.

Prince of Darkness is a powerful support for Tempo decks that rely on high health, slow Bloons to overwhelm the opponent. Combining Prince of Darkness with Bloons such as BFB, Golden Blimp, Soulstealer Bloon, or Lead Zeppelin can create powerful pushes that are difficult to deal with via damage.
Prince of Darkness's continuous healing allows it to support a large rush of slow-moving high-health Bloons, limiting the opponent from spreading their damage across the Bloons. Having very high-health Bloons (e.g. ZOMG) can further increase the opponent's difficulty of singling out the Bloons.
Compared to Healing Bloon, Prince of Darkness needs more turns for the initial investment, and cannot heal on the current turn. Both cards are commonly seen in Tempo decks.
Prince of Darkness synergizes with Soulstealer Bloon well, as the damage to your own Bloons can be negated by Prince of Darkness next turn.
The Zombie MOAB that this creates can be used as a shield for Camo Bloons due to its high health + the healing it receives from Prince of Darkness.
As a Monkey, it's vulnerable to Monkey removals such as Bed Time and Shrink, as well as Ghost Monkey which removes it (because it has no ammo stat).
Damaged MOABs can benefit from Prince of Darkness by raising their Health above their starting amount (after damage), however the Damaged MOAB is not often used outside of fast-paced Tempo, and the initial investment for Prince of Darkness may limit sending these Bloons early enough to gain significant value.
