Albeit being quite a savage-looking kelpie, he's a well-mannered guy in the first place. Once a tamed kelpie who lived with his human rider, Lewis followed the call of the wild after meeting Kiersten. He quickly adapted, and is not as docile as he once was. However, he will always prefer to solve situations without fighting, but will not hesitate to attack if he has no choice. Even if he lives in a wicked world, Lewis is surprisingly positive about the future, we can say he’s the very opposite of his mate.

Though, it's advised to stay careful when around him - especially when getting closer to his territory, as he can lost control in the blink of an eye and turn into a very violent stallion. His inability to keep calm in tensed situations makes him dangerous, but also stains his reputation among others in the crater.
