I always wanted to write something where a villain and a hero who are not connected in any way are buddies....
Like say Shocker's best freind was Angel.....or soemone.....The one guy is a street level Thug and the the other saves the world and the universe and stuff.......I always thought that would be cool......
On a similar note I liked the releationship that Dan Slott had set up with Constrictor and Hercules...and then Nighthawk......
For those that didn't read She Hulk and The Thing, basically Constrictor was being a bad guy doing bad things, Herc came along and beat the piss out of him, Constrictor then sued hercules and won a crap load of money. Herc then had to work for Damage Control.
Constrictor was now exremely wealthy and didn'tg need to be a ciminal anymore....he was hanging out with Nighthawk (Of the Defenders) and contemplated becoming a hero (Seen now in Slott's The Initiative) anyway, Constrictor was invited to The Thing's hero poker party, Constrictor and Herc were placing very large side bets on most of thier hands and in the end Hercules won a lot of his money back from Constrictor.......Great stuff.
