Airstryke

The character, created by John Ostrander and Jan Duursema, first appeared in Hawkman (vol 3) #3 in 1993.

Within the context of the stories, William Kavanaugh was given the ability to transform into a pterodactyl/man hybrid by a weapons company Meta/Tech and 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 here 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 on his mission. Airstryke was the first to question Blood on his plan. Brother Blood then shot and killed Airstryke for his hubris.
