Doug: I don't know about you, but I think it would have been really cool to have seen the Swordsman in a solo adventure book, as a sort of soldier-for-hire or adventurer -- maybe a treasure hunter. Many have commented that they enjoyed him as a bad guy in the Silver Age, and again as the loveable loser during his Bronze Age run in the Avengers. His comic book life might have been extended had he been given a try-out or some other extended run in a book he could call his own.
Doug: Similarly, at DC I think you could have gotten some mileage out of a solo book involving Colossal Boy. Giants are really eye-catching on covers, and the whole Science Police angle could have been used to some effect. Obviously various Legionnaires could have guest-starred, and to some extent writers and artists could have exploited a sort of Gulliver's Travels motif as Gim moved throughout the United Planets.
Doug: So how about you? Which characters from the Bronze Age, who were in team books only (so no Thor or Iron Man, and not even the Thing as he was for all practical purposes already in a solo book in Marvel Two-In-One) would you have liked to have seen in their own book? Or, maybe they could have carried half of a split-book... Let's hear it!
