So based off another thread I saw and the one I started in the Marvel Thread I wanted to see what Marvel Villains you want to see fight DC Heroes? I think this could be a fun topic.

I would love to see The Kingpin vs The Question (Vic Sage.) The Kingpin tries to take control of Hub City and the only one standing in his way is The Question. Maybe throw The Enforces in for this.
I also think The Kingpin could be fun to face off against Lois Lane. She is investigating a new crime boss in the city. Keep Superman out of it because he would crush KP in like a second. But would be great mystery for a Lois Lane book.

Wonder Woman vs The Enchantress and Executioner. Of course Loki would have to be thrown in. I think this one could be fun.

Justice League Dark Vs Mephesto.

So what are some of yours?
