Hypercooler

='THIS IS VERY IMPORTANT! DO NOT SKIP AHEAD FOR SPOILERS!'= Hypercooler is one of Four Bosses fought in Droids HQ that has the main gimmick of switching half the arena from water to ice and from ice to water.

Appearance
The Hypercooler looks like a Cryo Droid 3.0, having white and blue body parts, along with having white hair and antlers (?).

Behavior
Hypercooler acts like a typical droid, however the Hypercooler will swap half the arena from water to ice and from ice to water after a short indicator. After reaching half, Cryo Droid Spawners will begin to appear on conveyors above the arena.

Strategy

 * Obtaining Ice Resistance makes this boss much easier.
 * Obtaining Hazard Resistances is a great help to avoid having to deal with the switches from ice and water.
 * However, the Cryo Droid icicles will still be a large concern (not if you have ice resist it wont).
 * It's recommended to have a more zoomed at camera, because spatial awareness is needed to swap sides of the arena and the icicles that fall due to the Cryo Droids that spawn later in the fight.
 * Do NOT use any weapons, items or abilities that freezes water into ice throughout the fight. Otherwise, this will make the Hypercooler swap the entire arena into water, making the fight unbelievably harder.
 * If you have no Ice Resistance or Hazard Resistance, make sure to use the boxes that spawn in the arena. They make swapping sides a lot easier.

Trivia

 * Hypercooler is one of the most recent bosses added, in the 1.5 update.
