==Description==
'''Boss''' enemies are major bosses which generally spawn at the final wave. In some cases, an enemy may be considered a '''Boss''' enemy only for its first appearance. This gives it multiple immunities or resistances to various forms of stalling, even if these immunities are not visible under their health bar.

==Mechanics==
'''Boss''' enemies are immune to multiple effects, with varying degrees of resistance:

#[[Freeze Immunity]], making it fully immune to freeze and less affected by chillness.
#[[Stun Immunity]]; any period of slowdown is weaker on '''Boss''' enemies and prevents knockback.
#Immunity to poison slowdown, namely from the [[Toxic Gunner]], [[Biologist]] and [[Poison Ducky]], though it is still affected by poison damage or defense dropping.
#Immunity from the confusion effect when afflicted from a tower, namely the [[Jester]]'s ''Confusion Bombs'' and the [[Biologist]]'s [[Nightshade (Unit)|Nightshade]].
#*The confusion effect from the [[Confusion Ducky]] can still affect '''Boss''' enemies.
#Immunity to slowdown from the [[DJ Booth]]'s purple ''Drop the Beat'' ability.
#Immunity to slowdown from the [[Harvester]]'s ''Thorns'' ability (and by extension any thorns generated by [[Farm]]s).
#Immunity to a damage type, the [[Nuke]]'s fallout damage.
#*The explosion damage from the [[Nuke]] still affects '''Boss''' enemies.
#'''Boss''' enemies cannot have their defense dropped.
#*Due to a bug, burn and freeze defense dropping sources work on it. The [[Jester]] also works, but only on enemies which are not broken and allow it to reduce their defense.
#Immunity to being converted or slowed down by the [[Hacker]].
#Immunity to being slowed down by the [[Slime Trooper]].

'''Boss''' attribute also used to make enemies immune to these effects, but are not immune to them anymore:
*When first added, '''Boss''' enemies were immune to being set on fire by the [[Pyromancer]], to prevent them from being slowed down. This was removed in the [[Overhaul v1.0|Overhaul Update]], as the [[Pyromancer]] no longer slowed down enemies.
*When first added, '''Boss''' made enemies immune to the frost mark effect. This was removed in the [[Overhaul v1.0|Overhaul Update]], as frost mark was removed from freezing towers.
*[[Stun Immunity]] was originally [[Energy Immunity]].

While '''Boss''' gives enemies some immunities, they are not always the same as the regular immunity. For example, the '''Boss''' [[Freeze Immunity]] only makes the enemies partially immune to chillness, unlike the regular [[Freeze Immunity]] which makes them completely immune to chillness.

'''Boss''' enemies are also immune to some enemy abilities. For example, the [[Fallen Jester]] cannot apply [[Bloated]] or [[Nimble]] to them while the [[Slime]] cannot transform into them.

'''Boss''' enemies take 1.4x more damage from bottom path [[Juggernaut|Juggernauts]] starting at level 4B, and 1.5x more damage from maxed-out bottom path [[Juggernaut|Juggernauts]].

'''Boss''' enemies have a purple health bar appear at the top of the screen. Most sounds, with some exceptions like game music will also get quieter.
