I was going to go with something a little more elaborate but even with all of Tyki's powerhouse abilities and his insatiable mannerisms and charm I settled on his dæmon being a black panther. It's because despite everything he is a very simple man. He has basic needs just like everyone and she'll be just as laid back and lazy as he is with a warm temperament. Yet she'll enjoy the thrill of a good challenge while being polite and respective of others. She enjoys a good hunt just as much as Tyki and will be just as curious.

She's large and in control most of the time with black sheen for fur. In the sunlight one might see faint rosettes mark patterns on her body similar to a Melanistic leopard.

As for names I was thinking either Morticia, Hecate or Santana. I am really bad at naming things and open to suggestions.
