Zombies

Zombies come in types of shapes, sizes and forms. What kind of Zombies' should these ones be?

The 'classic' zombie that slowly shambles toward you, that no matter how many you kill, or fast you run a horde of them is always aproaching?

Perhaps it' the more modern take, super fast monsters with inhuman strength and speed that appear out of nowhere?

Or some other kind of zombie made just for erotica. One that tears the clothes of their victims and are actually intelligent?
