Throughout its history, DC Comics has introduced many characters, including numerous minor characters. These characters range from supporting characters, heroes and villains that appear infrequently, to characters that only take part in a single story.

Airstryke is a villain in the DC Universe.

Within the context of the stories, William Kavanagh was given the ability to transform into a pterodactyl/man hybrid by a weapons company Meta/Tech and he took the name Airstryke. Count Viper took advantage of these new abilities and used Airstryke to distract Hawkman while Viper tried to take command of the Justice League and thus the world. Airstryke and Viper were soon defeated and Airstryke was sent to Belle Reve Prison. He remained there until he was freed by Neron and was given the chance to sell his soul along with numerous other villains. Airstryke chose not to sell his soul and continued his life of crime. Eventually, Airstryke was returned to prison where he became a victim of Joker's Joker gas. Again, he was defeated and returned to prison. This time, he was sent to the Slab. During his stay, Brother Blood attempted to break all the villains out of the prison so they could assist him with his mission. Airstryke was the first to question Blood on his plan. Brother Blood then shot and killed Airstryke for his hubris.

Naif al-Sheikh is a spy and superhero in the DC Universe.

Within the context of the stories, Naif al-Sheikh is a Saudi espionage expert recruited by Vera Black to oversee and coordinate the Justice League Elite. He also acts as the group's liaison with world governments and ultimately the one that can, and does disband it.

In "Flashpoint" the story focuses on an altered timeline of the DC Universe. Flashpoint: The World of Flashpoint was published as a supplementary title looking at the larger setting of the primary series. The character was reworked as a member of the H.I.V.E. council, a group of world leaders trying to deal with the war between Aquaman and Wonder Woman that is devastating Europe.
