X-Men/New Teen Titans #2:
the team-up you didn't see


 

[in response to a letter in NEW TEEN TITANS #29, 1982]

[... ] sorry you didn't care for the DC/MARVEL crossover (although we did) but maybe the next one will be more your liking. What? Next One? Yes, we hereby announce the next TEEN TITANS/X-MEN meeting, scheduled for Christmas 1983, this time produced by DC. drawn by George Perez and written by me, Marv Wolfman. If you're interested in making suggestions as to Who the villains should be. please hurry. We're going to begin working on the story any week now. And since we really liked Chris's. Walt's and Terry's work on number one, well. Our job is going to be even harder. We went to produce the best team-up yet.

[from the NEW TEEN TITANS lettercol #38, 1983]

The second Titans/X-Men team-up will be published later this year if schedules are willing. George will be drawing it and Marv will write. It should be a goodie. One advanced bit of info is the villains: Brother Blood and The Hellfire Club. Interested now?

[The team-up was eventually scrapped because of a fall-out between Marvel and DC concerning JLA/Avengers, which was also being planned at this time.]
