We all loved old good hellhounds from kino , der riese and shi no numa. So why not bring them back in black ops 2 with buff.Black hellhounds so they teleport around and only way to kill them is to use explosion ,ray gun and maybe paped guns.another weapons wont work because they will doge that.Every time they hit you ,you lose perk or a clip of ammo they only apear like normal hellhounds but only 2-3 hounds per round solo.Then you killed them all you will get perk bottle and max ammo.
for first 3 boss rounds there would be normal hellhounds.
Backstory to them so then richtofen created first hellhound ,nazies thought that it would be good idea to create hellhounds and they turned war dogs into hellhounds.they use vr11 to calm them down and place in cages powered 115 and so when power went out and hell broke loose they escaped.
Video of my talking about this and showing black hellhound picture.
