Thunderhorse

The most loving demon of all time. He is similar to a god but more powerful than one. Be can sniff out thots from miles away and DESTROY them.

Person 1: What’s Thunderhorse?
Person 2: Don’t you mean WHO’S Thunderhorse? Why he is my god. I pray to him and thank him for everything once given to me.
