Male Mastiff Dog Names?

My family just adopted a 6 month old Bull-mastiff Rottweiler mix. he is HUGE! we aren't sure what to name him yet so suggestions would be great. We don't want anything overused.. like tiny, killer, zeus.. things like that. we would also like it to be a ONE SYLLABLE name, becuase dogs take easier to those. If you have anything unique that would be great. Thanks!
