AIM Burst

An AIM Burst is a phenomenon in which the AIM diffusion fields of espers connected to the Level Upper network are merged together and takes a physical form.

Background
Its existence is similar to that of Kazakiri Hyouka, as it is formed through the AIM diffusions of the espers that are connected to the Level Upper Network. However it seems to be more primitive in its actions than Hyouka. Like any infant it uses emotions to perform decisions or rather it is an amalgamation of the subconscious emotions of the people connected to the network and it lets out a screeching sound as if it was crying.

Because it is connected to the Lever Upper network when it appeared it caused convulsions on the comatose Lever Upper users, it is also shown to manifest the voices of the subconscious of the espers of the network. It is unknown if networks that are similar in function to the Level Upper Network are able to recreate this phenomena.

It is similar to an artificial angel just like FUZE=Kazakiri.

Appearance
The phenomenon initially took form of a giant levitating fetus with a halo upon its head and tentacles, its body was bluish in color and was covered in a nearly transparent brown layer. Whenever it is injured it would always regenerate, however its body does not retain its transparency and the body becomes a grotesque mass, becoming larger everytime it regenerates.

The AIM Burst has a rectangular prism core within it similar to Hyouka's, that keeps it together even if the network is disabled.

Abilities
It is shown to be quite powerful as it regenerated and grew larger every time it was damaged, can release a powerful energy blasts and has the ability to materialize and manipulate glass-like objects to attack an opponent and many others, though these abilities are derived from the collective abilities of the espers in the Level Upper network and are not innate abilities of the creature. The AIM burst creature can be seen as an primitive artificial angel, though due to the network it was born from made of mostly low level espers regardless of how many more are added to the network it still cannot match those with truly decisive powers, such as Accelerator, Kakine or Fiamma.

Toaru Kagaku no Railgun
The AIM Burst first appears after Kiyama Harumi loses control of the Level Upper network and causing the birth of the creature, it was noted by Uiharu Kazari to be in pain and seemed to attack only when provoked, it was also a very dangerous creature having the ability to regenerate. Misaka Mikoto does battle with it to distract the creature as it was heading for a nearby Nuclear Power Facility long enough for Kazari to disable the Level Upper network, it then loses its regeneration abilities and is subsequently defeated by Mikoto by using her "Railgun" to destroy its core.
