Anti Droid

The Anti Droid is an ally droid that only attacks other Droids.

Appearance
The Anti Droid has a very dark red body color with a bright red helmet and glowing red eyes.

Behavior
The Anti Droid may spawn naturally in certain rooms or through other ways such as from a Mystery button, naturally, a Mobile Phone or Wrath's Edge. The Engineer has the ability to spawn Anti Droids as well.

It deals contact damage to any droids it attacks and has scaling with the World #. The Anti Droid will chase the nearest hostile droid to it or Droid Spawner, receiving contact damage from the enemy droid. The Anti Droid attacks other droids similar to how droids attack players by simply running into the enemy.

When no hostile droids are present in its field of view, Anti Droids will stand still.

Trivia

 * The Anti Droid ignores players and neutral droids (other Anti Droids and Friendly Droids).
 * The Anti Droid can spawn naturally in certain rooms, especially in Stone Sanctuary. They become a rarer encounter beyond that though, especially in later worlds.


 * The Anti Droid attacks Friendly Droids as well if the player has entered The Darkness.
 * This happens even in the same world the third shopkeeper was killed in.
 * This, the Friendly Droid and the Lucky Droid are the only droids in the game that do not chase or harm players.
 * If an Anti Droid gets the Leaking or Exploding modifier, it is able to damage the player.
 * The Anti Droid can gain a modifier by Necromancer's second ability, which may buff its stats/harm the player indirectly.
 * The Anti Droid along with Undead Droid are the only droids in the game that chase and harm other hostile droids.
 * The Anti Droid is the one of the only droids that cannot be hurt by players, alongside the Undead Droid.
 * Whenever the player progresses to the next world, all alive Anti Droids will be teleported as well.
 * This does not heal the Anti Droids, unlike players.
 * It does not drop any circuits upon death.
 * This, all droids from The Darkness and the Weak Droid are the only enemies that have this feature (except enemies with the Cheap modifier).
 * However, Anti Droids can drop circuits indirectly from and  modifiers, and Iron Gear.
 * But if a Rusty Gear has been used without an Iron Gear, it will drop a instead.
 * The Sentient class shares its appearance with the Anti Droid.
