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 stuff getting real in Uncanny X-Men #211 as Colossus is not fooling around anymore...

Uncanny X-Men #211 by Chris Claremont, John Romita Jr., Bret Blevins and Al Williamson, takes place during the middle of the Mutant Massacre, where the X-Men show up in the tunnels where the Morlocks live to try to rescue them from a vicious attack by the superpowered villain group the Marauders.

During the battle, Colossus can't believe how much JOY that the Marauders are taking in the battle. Then something happens that makes thing change dramatically...





Wow.

That is awesome. Great job by Claremont and, I imagine, Blevins and WIlliamson.

You can tell how dramatic it is just by the reactions of the other X-Men in the next panel...



Rogue is stunned.
