Derrick Walker

Derrick Walker (previously Diedrick Wolf in the first concepts) is a main character of Five. His epithet is "Iron Wall". Derrick is an American duelist whose speciality is Action Duels, where he overwhelms his opponent by making them unable to move while they don't conquer his "challenges".

On his character

 * An energetic guy who loves sports. He is amazed by Nexus and by how intense and diverse the action-related modalities are there.
 * He could be kinda awkward, and tries to joke here and there but doesn't do it right and has a scary face so people think he's being serious. His parents divorced and he moved to Japan with his father when he was very young; being raised only by his father, a stern man, he may have trouble with being sensitive and reading the atmosphere. He's a good guy, nonetheless, only, he has trouble showing it.
 * Very loyal to his few friends but hardly opens up and trusts to other people. He's admired by his friends for his high spirit and dedication to sports even after he lost one of his limbs.

Backstory

 * Derrick got involved in a car accident in the past and lost one of his legs, as well as someone very dear to him.
 * He had a really rough time rehabilitating and was depressed for a while, but he finally found his salvation in sports. He uses an artificial leg now.
 * Despite his admirable spirit after what he's gone through, it could've made him a bit arrogant, and he looks down on other people's problems, because he thinks no one's suffered more than him or something.

Deck
Derrick runs a Hercules Deck, based on the twelve labours of Hercules. Each of his labours casts a challenge to the opponent, and only by surpassing the challenges they can reach Derrick and damage his LP.

Since most of the labours involve mythical beasts, Derrick primarily fights with powerful Token Monsters of said beasts, Summoned by their respective labour cards. He uses his Main Deck monsters and cards such as "Skill Drain" and "Token Stampede" to support his Tokens, making them even deadlier and harder for the opponent to cope with.
