5. Pizza Dog

(Hawkeye, Marvel Comics)

Lucky, aka Pizza Dog, aka That Dog Hawkeye Had, is one of those characters you don't forget once you read about them.

Introduced in the Matt Fraction/David Aja Hawkeye solo series, Pizza Dog is Clint Barton's inverse: lucky. His first appearance has him survive being hit by a car, and he avoids death on several other occasions, as well. Clint, however, shows time and time again that luck is one of the many things he doesn't have access to.

Pizza Dog, so nicknamed because he loves eating pizza, accompanies Hawkeye (Clint Barton) and Hawkeye (Kate Bishop) through their adventures, even following Kate to LA for the latter half of the book.

But if I had to pick one issue to show this dog's greatness, I'd obviously have to pick #11, "Pizza Is My Business". The story takes place entirely from Pizza Dog's perspective, as he wanders around Clint's apartment complex, trying to figure out what's going on. The visual storytelling is incredible, and the writing, art, and even the lettering come together to take the reader inside the mind of a dog. The issue was so good, it won that year’s Eisner Award for best single issue.

Pizza Dog forever.
