Zombie/Creature types/ Physical Appearance

[nikvoodoo]

Here's my question. How do humans become a behemoth for example from just a bite? Lets say a regular human gets infected by a behemoth. How does this standard human become a "10-15 feet, skinny arms and fat'ish/blubbery?"

That is the big debate. If we knew how that happened, we would have a better understanding of what the nature of this outbreak is. But there are disorders that cause humans to grow extremely large (See: Andre The Giant). So perhaps whatever is causing the outbreak alters the genetic coding of the victim.
