The CW's four-part DC Comics-based crossover is shaping up to be an insane event.Featuring characters from "Arrow," "The Flash," "Legends of Tomorrow," and "Supergirl," it will be a television event without precedent. We already know that the main heroes of each show will have to stand together against the alien threats of the Dominators, and it looks like they will need all the help they can get.RELATED: Supergirl Premiere Rockets CW Ratings to 8-Year HighIntroduced in the recent season premiere of "Arrow," it seemed inevitable that Wild Dog would be joining the CW's roster of heroes in the fight. Since then, Rick Gonzales conspicuously tweeted a photo of a pair of masks -- his and the Flash's -- implying that his character will be teaming up with heroes other than Oliver Queen. Later, it was confirmed that Wild Dog will be part of the crossover event.

“I can’t speak on that, but what I can say is that Wild Dog will be in the crossover, and he has a huge dislike for metahumans,” Gonzalez told ComicBook. “So we’ll definitely see him not exactly rub well with The Flash and Supergirl and that’s just another glimpse into his psyche and his ideas and thinking about the world and the idea that there are people out there who have these sort of powers and who they are. Instead of saying ’Wow, these people can do these things,’ he says, ‘no, I don’t like you because this is what you bring to the table. This is what you represent to me.’"

Starring Stephen Amell as the Emerald Archer, "Arrow" airs Wednesdays at 8 pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, John Barrowman, Willa Holland and more.
