10 Characters That Could Appear In The Arrowverse
1. Etrigan The Demon
Show: Legends of Tomorrow
Etrigan is a demon from Hell, as well as an antihero. At the end of Season 3, Constantine chastised The Legends because they opened a demon prison. With the prison open it would make all the sense for Etrigan to make an appearance in Legends since well, he is a demon after all. Just like Swamp Thing, Etrigan is also part of The Justice League Dark so that is another reason why he should make an appearance.
Something that could tie Etrigan to the Arrowverse is his human form. While a human, Etrigan's name is Jason Blood. If the last name sound familiar it is because Etrigan shares a last name with Sebastian Blood who many people think is one of the best characters from the second season of Arrow.
Etrigan would be an interesting character to introduce to the fold because he is literally from Hell. He can joke around and mess with people as some demons would, and other times he can be straight to the point. This type of personality would fit in well with The Legends as many of them, most notably Sara, have a similar nature. The CW has delved into metahumans, magic, and time travel so Etrigan would be a pivotal character in their quest to exploring demons and spirits.
