In "When We First Met", we spotlight the various characters, phrases, objects or events that eventually became notable parts of comic lore, like the first time someone said, "Avengers Assemble!" or the first appearance of Batman's giant penny or the first appearance of Alfred Pennyworth or the first time Spider-Man's face was shown half-Spidey/half-Peter. Stuff like that.

Today, based on a request by reader Joe M., we look at when the modern day Danger Room first debuted.

The Danger Room first showed up period in "X-Men" #1 by Stan Lee, Jack Kirby and Paul Reinman...

It first gained the name "Danger Room" the following issue...

The All-New, All-Different X-Men first saw the Danger Room in "X-Men" #94 (by Chris Claremont, Dave Cockrum and Bob McLeod)...

In "X-Men" #154 (by Claremont, Cockrum, Bob Wiacek and Joe Rubinstein), the X-Mansion was destroyed...

It was rebuilt ten issues later, while the X-Men were in outer space on an adventure involving the Brood. Xavier thought that they were dead. He added a new team of mutants (the New Mutants) in place of the seemingly dead X-Men. In "New Mutants" #1 (by Chris Claremont, Bob McLeod and Mike Gustovich), we see that when he rebuilt the mansion, he improved the Danger Room. This is the debut of the modern day Danger Room...

It later became sentient and later a member of the X-Men in and of itself as "Danger," but the Danger Room concept returned in the pages of "Wolverine and the X-Men" #1, only now the Beast had upgraded it to include the entire school!

Anyhow, there ya go, Joe! If anyone else is curious about when something first occurred in comic book history, drop me a line at brianc@cbr.com!
