Characters still exist, but paradoxically behave as if they don't when attacked. Equivalently, characters qualify which don't exist but behave as if they do in some aspect other than their interaction with attacks and abilities. To qualify for this type, a character needs to be stated to be immune to manipulations of the aspects they are nonexistent in due to their nonexistence. An example of that would be a character who is able to think, and hence has a mind, but is stated to be immune to regular mind manipulation as said mind is paradoxically nonexistent in nature. The character doesn't necessarily behave exclusively nonexistent in regard to attacks, but that is the only requirement necessary to gain this type. In terms of binary, where existence is 1 and nonexistence is 0, this would be part 0 and part 1 simultaneously.
