Xero Droid

The Xero Droid is a Droid that can be first encountered in Elemental Heights.

Appearance
The Xero Droid has gray limbs and head, but its face and torso are rainbow. The face and torso will also flicker between its own colors and other droids' colors if it spawns next to other droids. It wears a metal helmet strapped with green goggles.

Its 2.0 and 3.0 counterparts have the same face and torso, but each counterpart makes its skin darker than the previous one.

Behavior
The Xero Droid is neutral and will not chase players until it is attacked. When it is attacked, it will copy 90% of the attacker's, and will update their accordingly when the attacker's  changes, like if you equip a Katana. It will also jump whenever you jump, but will slightly slow down while doing so.

Combat Tips
Xero Droids have fairly high and high, making them dangerous.

When kiting Xero Droids (moving backwards while attacking it), always make large turns if you need to turn around. Making sharp turns will cause the Xero Droid to catch up to you and deal heavy damage. Attacking it while moving in a circle also works if you don't have a long corridor to work with, but try to make the circle as large as the space allows.

Using a Katana to fight this Droid is not a good idea, as it will also speed up to match the player.

Trivia

 * The Xero Droid is the only droid to not chase players until they are attacked.
 * Touching an inactive Xero Droid will still damage the player.


 * The Xero Droid and The Dark One are the only enemies that copy the player's.
 * The 3.0 counterpart of the Xero Droid has a very low chance to spawn from a mystery button in Mechtropolis.
 * However, Xero Droid 3.0 can naturally spawn in the Atomic Factory.
