Paranoia

In-Game Behavior
Paranoia will wander and occasionally teleport to random spawnpoints; sometimes after teleporting, it won't even move at all and teleport again. Paranoia may randomly have a blue light pulse from itself, and sometimes it may do it intentionally if anybody is nearby. The blue pulse actually acts a jumpscare attack, and the light itself goes out wide forward and behind Paranoia, but not as far left nor right. As soon as anybody enters Paranoia's sight, Paranoia won't actually do anything until 3 seconds pass, which is when it will charge; Paranoia will immediately gain a great speed boost and hunt down anybody it sees while in this state. Making contact with Paranoia only while it is charging will result in immediate death, If Paranoia chases someone for 20 seconds, it will give up at that point. Also, Paranoia follows anybody who enters it's sight. It doesn't matter if you leave Paranoia's sight or not, it will begin to follow you until you're far away from it.

EX Form
Paranoia now begins charging almost immediately, and it also attacks everyone both surrounding it and in it's view. It's pulsing light is also in the shape of a +, with it stetching wide out left and right now. Something new is that Paranoia also begins charging immediately if it hears a sound nearby, which making sound includes doing anything other than walking or using an item that doesn't make any sounds. Another thing new is that Paranoia can randomly summon mini Paranoias. Mini Paranoias teleport around, but only move while charging. Mini Paranoias won't follow anybody since they only move while charging, too. Despite looking like normal Paranoia, the mini ones are a little different: they still charge after someone has been in-view for 3 seconds, but they only attack those who were in their sight when they began charging. Mini Paranoias also can't jumpscare.

Trivia

 * Paranoia is actually based on an older version of itself in Slender Fortress.
 * Paranoia's EX form is Paranoia's current version in Slender Fortress. The mini Paranoias summoned are Classic Paranoia, though.
