What is a good unique dog name?

I want something not many people name their dog. I just got a Great Dane/German Shepard mix and he has some wolf in him too, I just don't know what to name him! It's so hard. I had a dog before him named Boomer and I loved that name. I just want something cool. Maybe in a different language or slang, that sounds cool and means something cool. Idk. Just say all the names you think of hahah.
