Dennis is the son of Virgil and Dakota Terrance. She was born on January 14, 2 years after his parents were married. He is a white fox with yellow eyes.

As a child, Dennis was a jokester who enjoyed teasing his sister and cousins. However, he did truly care about them and did what he could to make them laugh if they were sad. Dennis didn't like being schooled at home and liked being outside where he could play. He also thought learning was boring to some extent.

As a teen, Dennis assisted his parents and siblings on alcohol runs, usually teaming up with his friend Bo and best friend Rico on rum runs. He took his education a little more seriously but still enjoyed being a jokester.

As a young adult, Dennis became a great guitarist and a strong rumrunner for Lackadaisy.

As the "funny man" of the squad, Dennis is always there to make a joke, often at the expense of others. He is not always taken seriously and is easily sidetracked by beautiful girls. Despite this, he is incredibly loyal to his fellow teammates and will always be there for them.
