Mane: Long and windswept, teal in color with one side darker then the other.
Tail: Much the same as his mane, long and windswept, teal in color, one side darker then the other.
Eyes: Yellow and huge, yet often narrowed in a serious manner, enhanced behind glasses due to his farsighted condition.
Body: Dark purple coat with long, powerful wings. Medium-sized stature, has good strength (would still lose to any of the Apples in a fight though), and overall athletically fit.
Cutie Mark: A bright yellow eye, almost feline in nature, signifying his talent for observing things most other ponies don't notice, making him a brilliant guard and private eye.
Age (Baby,adult): Adult
Personality: Prowler is often a very serious individual. This does not stop him from cracking jokes or having a fair sense of humor, however. Around mares, he becomes very flirty, but more as a playful person. Were he to actually engage in a true relationship, he would not know what to do and, as a result, be very shy. That being said, during work, he gets very focused, usually to a fault. He's also cunning, but manipulative. He plans ahead for situations, but if it involves others, he never seems to explain to them what he's planning so that "they don't give it away," making it extremely hard, if not downright impossible, to work with him. He is prideful to a fault, but if he makes a mistake, he is self-criticising in a heavy manner. However, he is a caring sort towards his friends and is loyal, never out to backstab his way to the top. He also has a quirk where he often pushes his glasses back up with a hoof.
Likes: Mares, order, the night, and roses, scent and taste.
Dislikes: Criminals, chaos, and cider. The three Cs. Also his own worst critic.
History: Unlike most pegasi, Prowler was born in Canterlot. As a result, he did pick-up a sort of high class upbringing, but mostly stuck out in the unicorn-dominant crowds regardless. He was not really mocked for it, but it did wear on him a bit to feel out of place. Despite this, however, Prowler managed to go through most of his childhood without letting his spirits get down. He even managed to make a few friends. That was when tragedy struck.
It wasn't really the worst thing to happen, truth be told, but someone had robbed Prowler's family blind. With no clues as to who it was, the investigation was eventually ended after sometime and, with no way to pay for housing, Prowler and his family eventually had to leave Canterlot. It started Prowler's hatred for crime and all the things that could start it. The family managed to take up residence at Ponyville, with Prowler's parents still working hard, and life continued as per the usual.
Prowler, however, changed forever after that. It made him more cautious, more aware, and he began to search for things, train himself to notice things that others did not. When he managed to help a friend of his find an item stolen from her while she was at the marketplace, identifying the culprit and having him apprehended, that was when he earned his cutie mark. It was then he realized it was his fate to be an investigator and private eye.
So he grew, helping other ponies finding lost items. There wasn't that many criminals in Ponyville, Prowler noted, or that much crime to begin with. But whenever the rare beast decided to show its face, Prowler would always try to be there to put them in their place.
