All month long we will feature brand-new Cool Avengers and X-Men Comic Book Moments in celebration of their fiftieth anniversaries this month. Here is an archive of all the past cool comic moments that I've featured so far over the years.

Today we look at the return of the fastball special, courtesy of Joss Whedon, John Cassaday and Astonishing X-Men #6...

Okay, so the gist of the story is that Colossus is both alive and being held captive by a seemingly evil alien named Mork (or something like that). Mork escapes along with a young mutant as a hostage and it looks like he's going to get away.

Not so fast, buddy!

One of the top moments of the first story arc on Astonishing X-Men. John Cassaday really shined on that two-page spread.
