This was one of my favorite comic projects of all time. Both DC and Marvel combined to create a whole new comic book universe. Some of them were inspired creations - Dark Claw and Speed Demon being the best of the line. The rest all had something to offer fans of both companies and their characters. The final identity of Doctor Strange Fate is a cool surprise also. I would have continued to read many of these titles if they had ever been extended beyond the single issue.
Dark Claw was the combination of Batman and Wolverine and he fought a great villain in the Hyena, the combination of Sabertooth and the Joker. He was the match physically for the Dark Knight and that made the fights all the better.
