Sir Isaac Finnegan has slightly messily slicked back cream blonde hair with slightly tan skin, and tired dark brown eyes that turn dark crimson when hungry. He has large fangs that are permanently in his mouth and wears a white button up shirt, black dress pants, and a crimson vest for casual wear. Sometimes he will dress up, but only sometimes. He has angular features and is very tall, 6'7 and is of healthy weight for that height. He has veiny hands and sharp claws.
