Nice of someone to get some Joker wank in here, completely undeserved. Thats said its a shame Fisk cant bring a few of his lackies with him, like Bullseye for example. Also, classic Kingpin was pretty f'ing strong, it'd almost be like fighting Bane but with better h2h skills and a laser pimp cane.
Lex on the other hand I can see getting some good criminals under him. He'd get a lot of B-Listers working for him, like the Wrecking Crew, Absorbing Man (who is pretty beastly himself), Maybe some of the frightful 4. He'd also do more to make them a threat rather than just randomly sending them off to fight. The wrecking crew with tech power upgrades or Absorbing Man with a adamantium necklace would be pretty rough to handle.
