Gail Simone has revealed that she has worked on a Poison Ivy/Swamp Thing graphic novel - but that it may never be published. The writer, prompted by a fan tagging her and other creators in a request for the two characters to team up, revealed the tidbit on Twitter earlier this week.
"I have a graphic novel with this team up, but it's in limbo," Simone tweeted.
The writer didn't go into detail on why the book is "in limbo."
Simone wrote a major Poison Ivy story in 2014's Batgirl Annual #4, titled "When Pamela Gets Blue."
