Holographic monster

The Holographic Monster (Real name unknown) is a hologram an unnamed kid created using several traffic cameras as projectors from the episode Monster.

Appearance
The monster looks like a giant plant based organism with intertwining roots for legs. It hunches over, and has a faded and vein like complexion. The creature was unable to stand by itself so it had the appearance of walking on all fours.

History
The monster attacked Central City, with it's creator wanting to scare everyone, tired of being scared himself. The Flash discovered it was a fake after trying to trip the beast. Cisco was able to track it's creator's location. After Julian almost killed its creator, which the Flash prevented, Joe talked him out of using the beast.

Abilities

 * Fear Inspiring: The monster's primary goal was to frighten all of Central City. The beast's mere presence accomplished that.
 * Energy Depletion: The monster required a great deal of energy from the Central City Power Grid to manifest. This also allowed Cisco to quickly track the creature.
 * Holographic form: Being the creature is one big hologram, ropes and bullets pass through it.
