Description

The Hidden Boss is a large and fast boss that appears in Easy and Molten modes. It also appeared in The Classic Event. It is faster than the Molten. It has more health than the Necromancer, but less health than the Slow Boss. Towers must have hidden detection to target the Hidden Boss.

The Hidden Boss can be spawned from the Mystery Boss upon its death in the Easy and Molten modes.

The Hidden Boss was replaced by the Pro Streamer in Headache Headquarters.

Appearance

The current version of the Hidden Boss is a large humanoid with a waist, lower arms and lower legs in its rig. It is faceless and has a translucent dark grey body with a slime-like texture. It wears a black blindfold and cloak with a cape and sleeves, as well as black spiked braces with chains attached. It emits black smoke from its body.

The fifth version of the Hidden Boss was a large humanoid with a waist in its rig. It had a translucent black body and wears a black cape, cloak and sleeves along with a grey blindfold.
It would fade, becoming completely transparent, before fading back fully into view at regular intervals.

The fourth version of the Hidden Boss had a translucent black skin and a black pebble torso and legs. It wore a black cape and a large pair of translucent black horns with a shorter pair behind them. It had an emissive white scar on its face with two streaks leaking on the right side of it.

Strategy

  • While some splash damage towers like the Paintballer and Mortar cannot target Hidden Bosses, they can hit them through splash damage, if another detectable enemy is near the Hidden Boss.
    • This is very useful for towers which have a large explosion range, such as the Mortar.
    • The Rocketeer can be effective against the Hidden Boss because of its hidden detection and high DPS.
  • The Minigunner is an obvious candidate for defeating the Hidden Boss due to their high DPS and their hidden detection coming at a reasonable cost.
  • A Level 4+ Ace Pilot can provide hidden detection to towers that do not have it, making towers such as the Ranger and Mortar effective counters against the Hidden Boss.
    • The tower must be in the range of the Ace Pilot's runway for them to receive hidden detection.
  • You can use the Frost Blaster, Freezer and Warden to slow the Hidden Boss down.
    • You cannot use the Toxic Gunner as they do not have hidden detection.
      • While Sledger and Electroshocker do not have hidden detection, they can still indirectly hit the Hidden Boss if a detectable enemy is near it, though this should not be relied on as its quite inconsistent.
    • Due to the Hidden Boss's size, it can only be stunned by the Warden or frozen for a shorter length of time compared to average-sized enemies.

Trivia

  • When the Uber Mystery was in the game, it had a chance of spawning the Hidden Boss, upon its death, in Golden and Fallen modes.
  • The current appearance of the Hidden Boss is very similar to the original version of the Shadow Boss.
  • On some devices, the Hidden Boss may have transparent skin instead of black skin, with certain graphics settings.
  • The cape used by the Hidden Boss is a re-textured version of the Guardian of the Night Cape accessory from the Roblox catalog.
  • If the Hidden Boss is freezed by the Sledger, sometimes it will create a massive wall of ice.
  • Multiple Hidden Bosses can be seen as a chess piece in the Chess Board map, representing the Bishop chess piece.
    • One of the Hidden Bosses can also be seen hanging on the chess piece.
