Invincible is currently my favorite monthly title. The ever present blurb in the covers say it all, its "probably the best superhero comic book in the universe".
It's got an adorable lead character, an interesting supporting cast, engaging storylines, funny & witty dialog, excellent art and the most violent action sequences in comics today. If you haven't read this book yet, do yourself a favor and check it out!
