Could multiple bodies grant one a hive mind/sense if so give a example.
Well I can think of several examples (granted most of them from fictional sources but there is one massive example from real life). The first example i can think of would be The Borg from Star Trek. A massive hive mind made up of billions if not trillions of individuals all having their collective mental and sensory resources put together towards virtually any and every task. Granted The Borg have no sense of individuality and once disconnected from the Collective are nearly helpless in addition to suffering a severe detox as a result of having millions of voices in each others heads (made up of the remainder of the Collective). Another example from Star Trek would be the Binars. As a species they had become entirely dependent on their home planets master computer meaning that if anything befell the master computer the entire species would be forced into a state of torpor. Another example would be the Six Paths of Pain from Naruto. These are six corpses that have been not so much reanimated as made into automatons by the caster and each with Rinnegan meaning that all six share their fields of vision with each other. This isn't an example of a hive mind because all six Paths are reliant on the caster and owner of the Rinnegan to remain functional. As for the real life example that would the a World Wide Web (or the Internet as its more commonly referred to) which while it isn't a mind (yet) still contains more information than the human brain has the capacity to store. Once artificial intelligence is deciphered than the internet well become a mind and after that it wouldn't take much for it become an entity onto itself. The internet is a virtual construct with no physical form (strictly speaking) but it still interacts with via computers, phones, and countless other internet connected devices which we are becoming more reliant on every year.
So it's more of a hive sense that a hive mind
What do you think?
