Creatures, according to the story of Dungeon Defenders, are an evil group whose leaders were known as the Old Ones. The parents of the main Heroes locked this evil away in the Eternia Crystals. One day after their parents left for a long journey the Heroes accidentally released a small portion of this evil back into Etheria. These creatures are on a rampage to release their masters from the Eternia Crystal.

According to the story of Quest for the Lost Eternia Shards four evil creatures stole pieces of a shattered Eternia Crystal. The heroes set out to retrieve these lost four pieces, but find the evil creatures setting up arms with their own hordes of creatures. Here the heroes run into new and powerful creatures.

Bosses

Bosses are powerful creatures that are fought at the end of certain Campaign maps and challenge missions. The boss fight begins after the last non-endless wave of regular enemies, "The boss approaches..." message and then a countdown and (usually) a cinematic to introduce the boss (or bosses). The hosting player can skip the cutscene if they so wish.

The wave progress bar of enemies killed is replaced with a thick purple boss health bar, unless the fight consists of multiple boss monsters. During the fight, the non-boss enemies spawn nonstop. Many bosses have percent-based damage reduction regardless of difficulty setting. Some bosses effectively have invisible breakpoints to their health bar. These are intended to limit the amount of damage players can deal to the boss while it is in a vulnerable state (ex: when the Kraken has no tentacles).

Behavior

Bosses favor attacking heroes over physical defenses. None of them (excluding the Giant Apprentice) can damage Eternia Crystals. Most boss projectiles ignore Reflection Beams.

Immunities

All bosses are immune to: hero and defense knockback, Enrage Auras and movement-impairing effects (stun, slow, webbing, etc).

Most bosses can also see through the Huntress's Invisibility and the Ranger's Invisibility Field.

Creatures Difficulty Icons

The higher the color, the more health and damage the creature has. As the wave number increases, it is possible to get coloured creatures from the next difficulty (e.g. it is possible for Hard difficulty to have Insane coloured mobs).

  • Some creatures don't follow the pattern of colors. For example the Dark Elf Warrior has two purple icons.
  • While in Über Monster Fest on Insane, you'll see tiered creatures, such as OgreIconMedium.png with TowerUpgraded 2.png.
