Every town and region has their own. Yet the only one monster that can be found at every single newbie zone in the game is the decaying skeleton. Sure there are different variants depending on your region. Near Kaladim you will find decaying dwarf skeletons, near Akanon there will be decaying gnome skeletons, etc. They all have identical stats however and the only difference you will find between the different variants are in their name and size.
Decaying skeletons are a newbies dream.
Stat wise they are a reasonably easy kill even at level 1 as all decaying skeletons are level 1. Rusty weapons may sell for up to and over a gold piece each which is a nice sum of change for a level 1 or 2 character. More importantly they allow meelee types a chance to get a better weapon than their starting weapon. Beware however that decaying skeletons with weapons will hit quite a bit harder than the unarmed variety. Decaying skeletons are also desired for their bone chips.
