either as monsters or a boss. monsters should be something like trojan are just something big and strong that shows up on the map and have different types like ice, shock, fire, poison, shadow depending on area they are in.

for boss just have it be med size like snarbolax but hover a little bit off ground and make it do diving attacks or shoot sometype of big energy balls at u.
idk just suggestion anyone add more to this i'm not giving much thought to it right now just random idea putting out there.
