I know I complain about the blatant gimmickry of modern comics, but comics have ALWAYS had some shaky marketing schemes.
I was just playing with the Marvel APP on my phone, and I like to look up the appearances of my favorites to see any obscure comics I can hunt for when I get the chance. Anyhoo, I looked up the Beast (one of my faves) and noticed that his reprint solo story from #136 was his first furry appearance in Avengers. So Hank was force-fed to Avengers readers then brought into the fold.....clever marketing, I guess, but do any old-school Assemblers remember reading Avengers back then, and how was the reaction?
Hm, interesting, I didn't know that was a reprint issue. Did Englehart originally write that Beast solo too? Reading a bit about that story, the newly mutated Hank fashions a latex mask to wear so he can continue to 'appear' normal and work at Brand Corporation. That seems so out of character for him now, that's strange.
I've never read either version of that story but many moons ago, I did pick up a battered copy of #137, where Beast actually joins the team. I can't remember why I picked this issue out although the dynamics of the cover probably had something to do with it. (Beast leaping into action over a fallen Thor, what's not to love, right?)
Still, haven't read it in years so I remember very little about the story. May have to pull it out now to refresh some goodness.
