Steven Newlin is a recently turned vampire, and spokesman of the American Vampire League. The son of anti-vampire advocate Theodore Newlin, he initially continued his father's work after the murder of his entire family. He was a fanatic and a firm believer that vampires were 'ungodly creatures' who knew no 'humanity'. However, after becoming a vampire himself, he seems to relish his new undead status.
Newlin is first presented as somewhat of a well-spoken man with a friendly disposition that, while a little odd at times, is altogether cheerful. However, as the series progresses, we see that most of this is a front for his hatred for what happened to him and his family. He is shown to be unstable and unhinged beneath his amiable facade. As a vampire, this tendency seems even more pronounced.
Like virtually all members of the Fellowship of the Sun, Newlin was a Christian zealot who openly demonized vampires. His prejudiced and inflammatory speeches earned him much criticism. After being changed into a vampire himself, his viewpoint changed dramatically. He now relishes in being a vampire and has stated that his faith as a Christian has been strengthened due to his new status.
Newlin is also homosexual and is attracted to Jason and later to Russel, the latter of who's death devastated him.
Steve has the common powers and weaknesses of a vampire such as an infinite lifespan, superhuman strength, speed and healing. He has a natural affinity for glamouring and was able to glamour Jason. Due to his age, he is far weaker than her superiors such as Pam and Jessica. However, he has shown himself capable of overpowering her elder, Jessica, using a combination of strategy (pulling Jessica's hair) and his own enhanced vampire speed and strength. And was able to overpower Jason, a well-built young man, with ease. Steve was able to smell the Farie blood in the air. His weaknesses include a stake to the heart, silver and fire. Sunlight will slowly kill a vampire of his age. He is also shown, like most vampires, to have weaknesses when it comes to the Photokinesis power.
