Hellcanary

Hellcanary is the het ship between John Constantine and Sara Lance from the Legends of Tomorrow fandom.

Canon
Sara returns to the Waverider after dropping of Jax in 2017. It’s completely dark and she doesn’t notice John till he draws her attention. Sara asks why he’s here, John replying that he’s here to collect on Sara’s debt for returning her soul. Sara says his timing is awful, but John says it won’t take long. He quickly explains that he’s trying to exorcise a demon, specifically one that knows her name.

Fanon
Although not the ship fans expected to become canon after the announcement that Constantine would be on Legends, many still enjoy the ship. More ship it as a hook up like the canon, and prefer interactions as friends.
