This isn't obvious by going through these archives, but the last comic was made June 19th, 2006. This comic is being posted on August 12th, 2009. Yeah... it's been awhile.
Metroid, Samus Aran, Space Pirates, and all that other stuff are properties of Nintendo. Contra is a property of Konami. All other characters are property of their respective owners. Pretty much everything else is property of me, unless specifically noted otherwise.
