-The whole beastie can teleport between dimensions, freezing or otherwise manipulating time. This allows her to leisurely harvest human souls (seen in the image) or meticulously deconstruct robots.
-The head of this demon contains a large blossom on the top, which gives birth to a Demon Princess (fed on harvested human souls + robotic data), who can journey off (in the human dimension or otherwise), gain power, and grow to the size of the original.
-The tentacles/intestines at the bottom easily digest humans and machines, feeding the energy from their souls/data up into the head portion. Naturally, this lends them a death touch, as well as leeching powers.
-Giant decaying moray eel of some sort, out of which crawl beetle-like drone children, which attack her foes (including Angels, spirits, and other lesser Demons), using slash attacks, as well as dread and poison.
-Using harvested souls, this arm constantly reforms itself, cycling through learned magic spells or hacked robotic programs. This serves as an excellent adaptive defense, and the creature can make use of any magics or tech it comes across.
(out of 10)
Its physical strength among demons is surprisingly low, as the creature rarely appears in the same dimensional space as physical matter.
Infinite adaptivity, infinite memory, and infinite thought/computing speed. Can harness powers from humans and robots as soon as they are learned.
*Though adaptive, there is the slight chance of a destructive event occurring in an "off-planck moment", during which the demon is vulnerable. The odds of this naturally occurring at any moment are: (1.0 × 10^-88)/ N, where N=total seconds in the host universe. There is currently no way to measure exactly when this moment will be.
The ability to teleport and manipulate time allows this creature to move in several kilometers per planck second, movements which are unmeasurable by physics.
