Q: Enterprise...oh, yes. Weren't you one of the little people?

"Tom DeFaclo's mention of Thor and Thunderstrike brings back memories of a major trend (some would call it an epidemic) that was going on at Marvel at that time - namely, taking an established character and creating a "spin-off" version of that character. This spin-off would be very similar to the original character, yet different enough to justify its own existence and, hopefully, its own ongoing title. In addition to Thunderstrike being spun off from Thor, the USAgent was spun off from Captain America, War Machine was spun off from Iron Man, and the Fantastic Force was spun off from the Fantastic Four. So from a business standpoint, it made a certain degree of sense to try to do the same thing with Spider-Man. But creatively? Well, all I'll say is that THOR, CAPTAIN AMERICA, IRON MAN, and FANTASTIC FOUR are still being published to this day, and all of the spin-off characters are either dead, in limbo, or limited strictly to infrequent guest appearances."

"Up until a year ago, I had seen maybe three episodes of DS9. Back when the idea for the show was first announced, I clearly remember making fun of it with a college buddy of mine. We were under the misguided impression that because the recurring TNG character Chief Miles O'Brien was moving to a new show meant the spin-off would be about him, i.e., it would be Star Trek: The Chief O'Brien Comedy Hour."
