Behavior

Attack Phase: Dr. Terrible will wander around, occasionally throwing [Green Potions](/wiki/green-potion), [Turret Attacks](/wiki/turret-attack), or both. They are all dangerous and deal high damage, especially the [Green Potions](/wiki/green-potion) There are four Red Gas Spawners in the room that may also shoot waves of slow moving bullets during this phase. Each of these four Red Gas Spawners will not always fire. During this phase Dr. Terrible can be damaged.

Retreat Phase: Dr. Terrible will retreat to the bubble in the center of the room. While he is in the bubble he is invulnerable and he summons [Escaped Experiments](/wiki/dr-terrible-escaped-experiment), [Mini Bots](/wiki/dr-terrible-mini-bot), and [Rampage Cyborgs](/wiki/dr-terrible-rampage-cyborg) from the cages on the east and west sides of the room. The Red Gas Spawners will turn off during this phase.

"Rage" Phase: When Dr. Terrible gets low on health he will go into a rage phase. At this point, all the Red Gas Spawners will deactivate. Dr. Terrible will begin throwing potions much faster, usually two at a time. This phase is basically just the attack phase without the Red Gas Spawners activated.

Tips and Strategies

When minions are spawned during the bubble phase, prioritize the confusing pink enemies. If they are still around when the pink gas generators come back on, one bad confuse can send you through the deadly gases or into a Green Potion as it explodes. This is instant death for most characters. Because Dr. Terrible has no attacks other than spawning turrets and potions, it can be worthwhile to use the Staff of Extreme Prejudice on him, especially if he is paralyzed. Be careful that a Green Potion does not land on you. If you happen to be a wand class, you will be able to kill Dr. Terrible without him being activated, allowing for an easy kill. Go up to the boss room and continue to fire in the direction that he is in and wait till you hear the sound of the projectile hitting him. If you're not hitting him, get a bit closer but not to close that you end up activating him. (Your shots should be going off screen and hitting him.)
