Tom King's crisis center for superheroes and villains, Sanctuary, is an interesting concept in that the physical and psychological aftermath characters face isn't always carried with them from story to story.
Based on the Batman title, it looks like Poison Ivy is headed their for a visit to come to terms with her actions and inactions from The War of Jokes and Riddles and her recent story pitting her against Batman and Catwoman.
So, the question is...based on the stories and tales and characterizations you know, which other superheroes and supervillains would you like to see take part in Sanctuary? And why? Who do you imagine needs help and who do you imagine is searching for redemption?
