Fin Fang Foom Billboard – Iron Man 2

Speaking of billboards alluding to fan-favorite characters, Marvel included one in Iron Man 2. Their billboard, which Iron Man flies past at breakneck speed, featured artwork of Fin Fang Foom, a giant Chinese dragon and a classic member of the Armored Avenger's rogues gallery. As fantastical as the Marvel universe has become, it's doubtful we'll ever see Fin Fang Foom show up in the flesh on screen, leaving this billboard as nothing more than a cool nod to a famous and rather badass comic book character.
