Zombies are anatomically impossible... You can move your limbs without a functional circutory system. No heartbeat, no movement. Let alone the fact the brain need the electrolytes your blood pumps to it.
@Barry Dylan, but parasites are possible. Something like cordecyps from the last of us could be a real thing. There are plenty of parasites that take over the brain of the host, make said host live for the parasite, then go die and be feeding grounds for babies
@Ye Ol Redneck , But zombies have been in multiple cases something that can withstand any amount of damage aside from head trauma. Parasitic infection is a different story, plus last of us zombies have a different form of infection.
@Ye Ol Redneck , brain prions have already been a thing in South America where people consume the brain of some animals and even slain enemies in battle.
@Ye Ol Redneck , actually that already kind of exists. There is a fungus in south america that goes full "The Last of Us" on ants and controls their body to move the fungus to a habitable spot for it and then kills the ant and uses it for food
@Barry Dylan, dead bodies move all the time. Especially during decomposition. Smaller muscles can contract and in some rare cases dead bodies have sat upright temporarily . And some bodies can even moan due to left over gasses trapped in the lungs
Watch me trip, watch me die die
