You know the arguably biggest superhero movie spoiler of the summer has achieved total "yeah, yeah, we know, we know" status when it's used as a promo clip to promote a Blu-ray/DVD release. Despite the fact that a bazillion fans saw The Avengers movie in theaters, however, we're going to attempt to stay spoiler free a moment longer and just mention that a clip revealing the villain behind Loki's Army and scepter is now online. If you've seen the movie, the vid will give you a chance to relive some excitement before The Avengers arrives on disc/download on September 25. If you haven't caught the film just yet, though, you've been warned about the spoiler-y nature of this clip. Hit the jump to watch the villain reveal from the end of The Avengers!

One more time: Spoiler Alert!
