Oooo I like the sound of Crest of the Stars. I actually watched Black Lagoon's first episode and it didn't really captivate me since the main character seemed like a mega-wuss. Does it get better in later episodes?
Black Lagoon's all I can think of right now. Heroic sociopaths at work. With guns.
Also, the Crest and Banner of the Stars series has basically decent protagonists, who happen to serve in a galaxy conquering army whose idea of peace keeping is "Solve this by yourselves or we blow up your planet".
I'm tired of goody-goody main characters in anime (too over done). How about some anime with assholes for main character... such as Death Note or Code Geass (although Lelouch isn't asshole enough for me). I really liked that guy from Bastard.
