What should I name my new great dane?

Alright so I'm going to pick up my little great dane puppy tomorrow and I'm trying to think of a name. I'm kind of picky so i'll give ya some insight on a type of name I'm looking for. I want a name that is manly. I have another great dane named "Astro", so I'm kind of looking for a name that can go good with his name as well if that makes sense? I think you know what I mean, but anyway let me know what you guys think
