I'm a big fan of the Retronauts gang over at 1up, so when Retronauts contributer Nadia Oxford gave us a heads up that she had gone and blogged about the fascinating world of Mega Man intros, I just had to post about it. In her post, she discusses some Mega Man intros from the main series and points out her favorites such as Mega Man 4's intro (emphasis, mine):

By the time Mega Man 4 rolled around, the NES was capable of some pretty heroic graphics. A little movie explaining the origin of Mega Man preceded the title screen, and it was epic for my ten-year-old mind to behold. Suddenly, the little blue robot had humanity, purpose, and a history. Of course, he had all that in Japan from day one, while America just got box art starring the Chupacabra. Nevertheless, I still love the train-riding bit, complete with tunnel lights whizzing by. Tickets? Mega Man's on a mission to save the world. Shove your tickets.

Chupacabra indeed. Of course, we can't all be perfect and there are some bad apples in the bunch (Mega Man 3, where you at?).

Take a look and let us know about your favorite intro! As for mine? I'm partial to Mega Man 2 and Mega Man 9.
