This is the latest in a series (of indefinite length and regularity) of pieces looking at particularly odd/strange/interesting instances of retroactively connecting different comic book characters (for instance, Uncanny X-Men #268 retroactively established that Wolverine knew both Captain America and the Black Widow from World War II). Here is an archive of all of the past pieces.
Today we look at the surprising connection between Deadpool and the X-Man known as Banshee!
Banshee is a fascinating subject for this type of thing because when you look at the various members of the X-Men, Banshee is right up there with Wolverine in terms of having the biggest blank slate in his past. He is older than most of the X-Men and we know very little of his past before he became a member of the X-Men, so there's lots of room to say, "Oh hey, did you know that Banshee knew ____?"
That's exactly what happened in Deadpool: Sins of the Past, a 1994 mini-series that featured Mark Waid's debut work for Marvel Comics. The mini-series was initially drawn by Ian Churchill and Jason Minor. In the previous Deadpool mini-series from the previous year (by Fabian Nicieza and Joe Madureira), we had established that Deadpool was familiar with Black Tom Cassidey.
In this sequel series, Cassidey's cousin, Banshee (along with Banshee's daughter, Siryn), tries to find out where his cousin has been taken following the events of the previous series. During this point, Banshee comes across Deadpool, who is also about to be taken prisoner by the same people who have Black Tom.
In the process, we learn that Banshee and Deadpool know each other...
The "Fabouk affair" is explained in the following issue, with artwork by Lee Weeks and Bob McCleod...
Banshee seems to know Deadpool from beyond that first meeting, at least based on the dialogue in their meeting in issue #1, but if so, those interactions have not yet been elaborated on.
While Banshee and Deadpool have not had much interaction since, Deadpool and Siryn became connected for many years after this initial meeting.
