The show is a wip btw. Some things might be added or removed.
THE IDS ITSELF (symbol, not show):
It can destroy some materials (but it can't rebuild material) and rebuild itself.
It can be destroyed, but it'll be hard to do so.
It renews itself every 2-3 years.
It's "spikes" represent beings who inherited or gained the symbol. Currently, there are 9 creatures. Since 18 is 9 multiplied by 2, it represents that: "two people who gained the IDS from one way or another are equal; two robots who have it could die in the same way, and they may or may not be parallel to each other." 18 may be the amount of robots with it, if it doesn't get controlled.
It can also be gifted, but only in extreme cases.
If you change its' size, it can be worn as a bracelet, ring, overall, an accessory.
It contains robots' organs if it dies; and combines it into a heart: Turning oneself off (/nsx) to sleep doesn't count.
The heart (located inside of the IDS) is immensely powerful, containing all the extra memories, heartbeats, voices of a dead robot. (but it can only choose one)
The heart is like a supercomputer in the form of a "heart with some other stuff" that contains all the operating systems, voices, memories, heartbeats, and wires.
The heart has no face externally.
Both can murder, but the IDS has murdered more people.
Both taste differently, depending on which OS the AI that "tastes" it has.
Due to the various operating systems inside the heart, it's AI can fail processing sometimes. but! It continues doing whatever it's doing.
