Like the title says. I had the first immigrant wave and one of those immigrants is called a "ranger berserker" went after arriving absolutely nuts, let out a roar and transformed to a red dragon breathing fire on everything in sight... The dwarf in question is over 260 years old (world is 150 years). So can someone explain this to me? And what to do with the now naked dwarf who transformed back 
thats odd, but because its DF u can probably have him stored in a single tile room on the outside of the fortress, and when a siege happens, lock the doors, and then when he transforms open up the door to the outside for him only, and hill go on a rampage. oh, and he might be some sort of god or demon? idk.
