Hologram Probe

Hologram Probe is a reccuring enemy in the Crash Bandicoot series, where it shaped like a spherical robot with a telescope-like eye, and it is seen on various occasions randomly floating.

Story Games
The probes have reccured as an enemy seldomly only in the story games, working for Cortex to produce holograms, or patrol the perimeter. They also possess no attacks whatsoever.

Crash Bandicoot (Game)
The Probes are first seen on Cortex Island in the level Heavy Machinery, where they take on a Basic pattern of up and down, and can only be defeated with a Spin, which has to be timed depending if they are above pits. In the Generator Room level, they go around in Circles, and at one pont with two of them. They can also be seen in Cortex Power, where they have a left to right pattern while above Toxic Wate pools. They are also found in Castle Machinery, where they repeat their Basic patterns.

Crash Bandicoot 2: Cortex Strikes Back
The Probes now project Holograms for Crash in the Warp Room and seem as a sort of breif Ally, as they are not in the final levels. During Hologram Messages, a Probe will circle around the Hologram projecting it through their eye. They project all the Holograms but not just for Cortex they also project Coco and N. Brio's messages.

Crash Twinsanity
The Probes return in Crash Twinsanity after a 7 year absence from the Series, but with a new Dark Red color to them. They are seen only in Ice Climb where they simply float in the same place their in, but outside the Caves, they move from left to right over Steaming Pipe. If they are hit they will fly and hit the ground sparking a disappear in a Flash of White Light.

There is another version of the probe seen in the enemy gallery but it does not make an appearance, it was most likely cut. Judging by it's design, it looks like Crash would have use the slide kick to defeat it.

Changes
The Probes where colored Rusty Gray with several small vents on themselves and a Telescope-like eye, and in Crash 2 the Crash 1 model was used. In Crash Twinsanity they had a new Red color, lacking any differences.
