As we saw in the last post, Paul Sloane was notable as an impostor Two-Face because he was the only one who was genuinely scarred, genuinely nuts, and genuinely thought he was Two-Face, while the others were just pretenders trying to frame poor Harvey Dent.
Once Sloane was defeated, he sank into obscurity until 1987, when Mike W. Barr brought him back for this story, which also throws Harvey into the mix in a reversal of the typical Impostor story. As this cover might indicate:

The following are excerpts Detective Comics #580 an #581, by Mike W. Barr (who writes one of the corniest Two-Faces ever, full of terrible, smackable puns) with art by Jim Baikie.
( Two-Face vs. Two-Face behind the cut! )
The idea of a new Two-Face is an intriguing prospect that should have been utilized while Harvey was "healed" in the years between Hush and Face the Face. A new Two-Face shouldn't be a carbon copy of the original, but should rather be used to explore themes of duality, fate, and justice in ways that Harvey Dent can't (or shouldn't), while Harvey himself could have gone on to have much more interesting character development as a wild card antihero.
That was the last appearance of this Paul Sloane, but thanks to a wonderful gem by Ed Brubaker, we're not done with the character just yet.
