Tony Stark and Rocky Balboa aren't the likeliest of allies. But when a United States sports icon like Apollo Creed is taken out with such ruthless efficiency by Ivan Drago all because Tony has "successfully weaponized boxing" and has created a deadly enemy out of Ivan "Whiplash" Vanko, conventional wisdom goes out the window and unlikely alliances are the only logical solutions.

Such is the plot in "Iron Man IV," a mash-up parody video featuring some terrific popular culture cameos from James Brown, the "Teenage Mutant Ninja Turtles 2: The Secret of the Ooze" gang and Johnny Five. Really, there are too many cameos to call out - there's even a quick nod to Zangief that the makers of "Street Fighter Legacy" would approve of. Even if I could mention them all, it's really best to just see them for yourself.

Check out the "Iron Man IV" trailer in all of its glory after the jump.
