I found out about the Dragon fan-theory back in the 90's. I was getting more hardcore in my Iceman fandom and was searching the internet for everything I could about the character on a daily basis. I knew the Tatsu(Dragon) clan had factored into two issues of X-Factor and two issues of Uncanny X-Men, all with Iceman, and was looking to see if there were more appearances of the Tatsu Clan and if Iceman was involved. I ended up on a website where a guy was posting about what a weird coincidence it was that Iceman, whose surname meant Dragon, had ended up in a relationship with a girl(Opal Tanaka) whose Clan name Tatsu also meant Dragon, and this other guy was like 'coincidence? Let me tell you something'. I started digging into it as much as I could but finding out anything was hard as most people seemed to have never heard of it and of those that had most didn't know much more than I did. It seems to be a factor in a lot of Iceman stories over the years in ways large and small. It's likely the reason Iceman had wings in the "Frozen" arc in Astonishing X-Men and briefly had a dragon-headed-form when he 'ate' Thor. Also the reason he hid his ex-girlfriends away in an ice-cave, Dragons in mythology routinely hide treasure and things precious to them in caves. We even had an alternate-reality Iceman who was a god called Draka...

Finding sales data about Iceman FIRST mini from 1984 is hard, but here's this from over at Comichron.
Iceman #2 from 1984 ranks 13th in overall sales for the month! It's selling 37.4% of what the top selling original Secret Wars #10 did(by comparison Uncanny X-Men #190 ranked 2nd at 80.9%)! And that's with Iceman retailing at $.75 in a market where most books were still $.60.
To give that a bit more context...
Each year, Marvel(and all other publishers) were required to publish the sales data of each ongoing series, and it was usually included in the letters page every 12 months or so. This would include things like the Print Run and the Paid Circulation. Using an average for Uncanny X-Men for the years 1983-1985 and given the sales trend, Uncanny X-Men was probably selling around 350,000 copies a month when Iceman #2 came out, which would put Secret Wars #10 at around 433,000 copies, and with Iceman #2 at 37.4% of that, we are looking at estimated sales for Iceman #2 at around 162,000 copies. While there is no known data for the first issue publicly available, number #1 usually sell at
much higher numbers than #2s which would likely put Iceman #1 at or near the top five for it's month.
Natasha tried to rebuild the Avengers in the wake of Onslaught in Avengers Annual 1999. It was just one panel , but Bobby, Hank and Warren were the first people she reached out to to join. Hank as a former Avenger and Bobby and Warren because they were her former teammates in the Champions. They all declined feeling the X-Men needed them more.
I'm going to shoot you a PM so we don't derail this thread.
