This week, the internet promptly descended into chaos when Marvel dropped the first trailer for Avengers: Infinity War.

In 2016, the writers revealed that there are up to 67 "available" characters that have appeared in prior Marvel movies, and that's not even counting the new characters they might introduce. While the writers said not all of these heroes will appear, it's still safe to assume the number will be very large. Here's who we spotted in just the first trailer alone.
