With John Constantine's inclusion in the Arrowverse, a few more DC Comics characters may be seen in "Arrow" Season 4.

According to Comic Book, "Arrow's" John Diggle may take on the identity of Gangbuster. With the alter ego Jose Delgado, Gangbuster is an advocate for troubled youth who lost his patience and opted to combat gang violence and villains in an armored suit.

A possible issue to Gangbuster is that Hispanic superheroes had not actually gone through the screen to date, as per Comic Book. The publication added that including a character that signifies multiplicity without the need to change the character's race with that of a new actor would have been great.

Aside from "Arrow," Delgado is also a possible inclusion to CBS' "Supergirl," since the character is linked with Superman and Cat Grant, whom he had dated for a lengthy time span in the comic books.

Jim Morrigan or The Spectre, who was portrayed by Irish actor Emmett Scanlan in NBC's "Constantine," would also be a great addition to the Arrowverse, as per Comic Book. The character appeared in some of the series' episodes as the agents of God's wrath. With Season 4 touching elements of mysticism, Morrigan could be seen in the series.

Meanwhile, Constantine could be a character The CW would have wanted to use more often, according to Comic Book. Constantine is set to appear in "Arrow" Season 4 Episode 5, which is entitled "Haunted," marking a crossover between the "Arrow" and "Constantine" realms.

"Arrow" Season 4 Episode 5, "Haunted," airs in The CW on Nov. 4.
