Metroid, Samus, Kraid, and the rest of 'em are all property of Nintendo, who to my knowledge wouldn't do anything such as sue me or shut poor Planet Zebeth down, because they're so damn nice, and Metroid kicks ass : }
This particular comic strip was made solely by me, by that happy little program known as KolourPaint. Yes, the one that everyone runs in fear from. That's why the comic looks the way it does.
