So this is what I'm working on. It's the undead canine evolution line. And you can see from how complex this is that Daemon evolution swings more to the Digimon side of things. Also the designs for the darkness, eldritch and infected lineages are very Bloodborne inspired.

So the undead canine line comes in four elements, darkness, eldritch, fire and poison. They also have an additional lineage when merged with Tentacite. You start out with Skullpup as your common level. It evolves to Zomdog as its intermediate form. Then things start to diverge. If you merge Zomdog with Tentacite then it becomes Infected Zomdog and then Hostvulf which then evolves to Moon Beast as its supreme form. If you don't infect Zomdog then it evolves based on its element. Darkness and eldritch both become zombie werewolf. This lineage splits apart again in the ultra form. Darkness becomes Kludde, which is a werewolf - vampire hybrid, and eldrich becomes Eldrich Werewolf (I might come up with a better name for that one). Both of them also evolve into Moon Beast. Moon Beast itself may end up with a further legendary level form.

If the Zomdog is fire element it evolves into Hellhound and if it's poison it evolves into Spine Back Hellhound. Both of them have their hellhound ultra level forms. They both evolve into one of the four Apocalypse Dogs for the supreme level form. I'm not sure what factor determines which Apocalypse Dog they become, it might be random.

Also I was going to put Anubis hound in this lineage, but couldn't find a spot for it, so I might put it elsewhere.
