Charred Zombies are mobs similar to normal zombies, except that they are in grayscale color, have no weakness to fire, and have 6 health ().
Despite their resistance to fire damage, Charred zombies can still catch on fire (which they will not be damaged by) and will still flee from the sunlight, despite not being damaged by it.
Charred Zombies do not spawn under normal circumstances, but if a Mummy is lit on fire, it will burn away and leave a charred zombie in it's place.
Charred zombies can also spawn during a mob siege, but only if the mob siege occurs in a volcano biome or burnt down oak forest biome.
