Lastly there are the beasts of chaos. The beastmen are a very weird force (not as weird as the daemons of course) but still weird. They can get a variety of beastmen troop and they also get some big scary monsters like Minatars, trolls, orges, and dragonorges. They really don’t get any mount besides the chariots that they have, but they don’t really need them because they can move pretty fast.    

 
     
here are some beastmen.
the creation of the beastmen began with the collapse of the northern and southern polar gates. when the elves pushed back the magic the world was filled with unnatural mutations, like griffins, trolls, and the giant rat beings known as Skaven. among these mutants where the beastmen, or "The Children Of Chaos" as they call themselves. 
there is only on word for the Beastmens advantages, big monsters. the beastmen get a number of special monsters to help them cause as much destruction as they can cause. and you can get a minotaur lord and get as many minotaur as you want.
but some bad news is that the Beastmen don't really get any mounts besides chariots. also the big monsters tend to be costly and are shot down. also if you don't getthe smaller units of beastmen you will be outnumbered and overrun.
