Killer Babies

Killer Babies are reasonably common in Xor and Psychon and come in several sizes. Re skinning an ogre as a mid size killer baby needs very little work mostly they don't like treasure. On Xor babies might congregate around terrain with giant breasts.

These creatures are usually abandoned in sewers of cliffs and are born to mutants or those with the mutant taint. They can see in the dark. They rarely get bigger than 20lb and will find each other and congregate in a pack of 3d4. The boss baby might have 3d8 and a d6 bite. Sometimes a baby will pretend to be cute an lost as a trap then the other babies will leap from hiding. Some babies have other mutations and abilities. Sometimes a kindly witch will change their nappies. Babies might collect shiny things and will eat all kinds of stuff they find in dungeons and may have treasure in their nappies or piles of faeces in their lair. Babies might be bribed with milk, rattling or shiny objects. Can be tracked by slime or faeces trail

These huge beast start as regular babies that scream and demand so much food they are abandoned usually in the wilderness. The ones dumped in sewers run out of rats and get too big and go upstream looking for bigger game. Giant babies are attracted to human settlements and usually the locals will call adventurers or knights or the militia to drive them away. Giant baby mutations appear once they are bigger than a human and mostly they are cosmetic. They will destroy houses and any human made structures and kill farm animals by grappling and chewing them.
