Watcher

The Surveillance Robot, also translated as "Watcher" in Kingdom Hearts 358/2 Days, is an Emblem Heartless that is found in Kingdom Hearts II and Kingdom Hearts 358/2 Days.

Kingdom Hearts II
The boulder which hit Goofy while trying to protect King Mickey was dislodged by a Surveillance Robot, rendering him unconscious.

It is one of the only two species of Heartless that Sora fights in the Battle of the 1000 Heartless.

Design
A Surveillance Robot is a bronze-colored, funnel-shaped, mechanical Heartless with a diamond-shaped opening in its front, exposing its glowing, yellow eyes. Two black, rectangular guns are mounted on either side of its body. Each of these guns sports a silver, pyramidal spike on both of its ends. There is a silver ring that acts somewhat like a hovering around its base, despite not being directly connected to the Heartless. This ring bears a vague resemblance to the top half of the Nobody symbol. It has a silver spike on the top of its head, and its Heartless emblem is just below the opening for its eyes.

The Surveillance Robot's name obviously refers to its mechanical nature. "Surveillance" may refer to military surveillance, a systematic set of observations, or simply "surveil", which means "to continuously monitor". The Heartless's ability to levitate would presumably make it better suited for surveillance than other Heartless. "Watcher" holds a similar meaning, and can also mean "guard".

Strategy

 * Attacks
 * Twin Laser: Fires two white lasers.
 * Mow Down: Spinning saucer ring attack.
 * Charge Laser: Fires multiple red lasers.


 * Reaction Commands
 * Snag: This Reaction Command has Sora grab the Surveillance Robot and shake it.
 * Sparkle Ray: After Snag a large, powerful ray of light larger than the Robot itself will erupt from it, and Sora can point it at other enemies before throwing it back into the air. This Reaction Command does not damage the Surveillance Robot itself. It is also worth noting that although this is seemingly the Surveillance Robot's most powerful attack, it cannot use it against Sora.

The Surveillance Robot is not a very difficult opponent, and can prove very useful with its Sparkle Ray Reaction Command. Sparkle Ray won't damage it, however, so Sora will have to attack it directly However, this is especially helpful in the Battle of the 1000 Heartless. Since Sparkle Ray is very powerful and it doesn't damage the Surveillance Robot, Sora can literally use the same Surveillance Robot again and again until all the Heartless are destroyed.

In Kingdom Hearts 358/2 Days, the Watcher is more annoying in the sense that it shoots lasers randomly and may shoe-glue Roxas, preventing him from jumping. It is possible to deflect the lasers back at it, but it will counter with a powerful laser that can't be blocked. Either way, it is still a very easy opponent.
