Zombie werewolf, it is by itself in a empty town or can have a chance to spawn with death and fight along side it

Town zombie werewolf: werewolf would be sleeping in the church and once you step foot in the town the churches doors would explode away allowing this house sized werewolf to escape sorta like how the Zombie boss in still water enters, it would walk on all 4s due to its huge size, it would be as tall as a normal house but much wider and longer, when you kill it, it will drop a tooth that you can sell for 50$ and if you go inside the church there is 3-8 bonds with a random item that you can buy from the abandoned churches, the boss will have 2000 hp and do enough damage to put you into the red, when you kill it its body turns into a solid, you cant move it or bag it due to its size, the only way you can move it is if you reanimate it with the sword or mask the town that he spawns in can appear from 75k-50k

Zombie werewolf that rides with death: much smaller just about bigger than the normal werewolf, it will do normal damage but will have a heath draining affect simular to being on fire, this only happens 1/5 times, it is a bit slower than the normal werewolf but has 100-200 more health. And would have a chance to spawn with death
