Nice one.  I didn't recognize 5 or 9, but they were easy guesses due to the art style.  Who are they?

This was fun, but you should have included some love for the MOTHER series. They each feature the boy and his dog partnership.

LET'S GO POPPY.

Chris - 5 is Galford from the Samurai Shodown series of fighting games. 9 is the Vanquisher, one of the character classes in Torchlight, a Diablo-style dungeon crawl.
