St. Peter is a pale-skinned humanoid angel with curled, short pale-blonde hair, turquoise eyes with no pupils, and sharp royal blue eyebrows. As an angel, he sports a white halo above his head, and a pair of large feathered wings on his back which are celeste blue and cream.
He wears a light blue vest over a pale yellow shirt with the long sleeves sporting dull golden cuffs, and a light blue skirt with dull golden detailing that forms into a cross at the hem. He also wears a pastel red bowtie and dull golden flats.
Personality
St. Peter appears to be a friendly person overall. He is welcoming to newcomers and visitors, even if they're demons. He is somewhat flirty, enjoying the company of attractive people.
However he is somewhat prone to being startled, freaking out when Charlie reveals herself to be Lucifer's daughter, where he lets a cuss word slip in surprise.
He may be a little absent-minded or he just doesn't pay much close attention to some things, as he doesn't seem to notice Charlie's last name "Morningstar" to be the same "Morningstar" in Lucifer's name, making him unable to make a conclusion that she is Lucifer's daughter until Charlie told him.
In "Storyteller," he seems to take great pride in watching Heaven's gates, bragging about how he watches the door "very well", much to other angels' annoyance.
