Tarco

Tarco (タルコ, Taruko) is a Demi-Human that was introduced as a new character in Re:Zero Lost in Memories when Emilia, the members of her camp, and Wilhelm were all sent to the Demi-Human War 50 years ago.

Appearance
Tarco is a middle-aged man with bushy white eyebrows, a scar on his left side of his face, and long black hair that has grey and white strands closer to the tips. He also holds a braid adorned on his right side of his hair. Due to his Demi-Human blood, he has fangs and wolf-like ears on his head. He wears light armor with fur on the inside, a heavy shoulder guard his right shoulder, and also adorns himself with a long blue cape.

In his Beast form, he has grey and cream white fur on his body. Additionally, he has features similar to Ricardo with black hair on his chest and arms, but also holding tusks on the sides of his mouth. He has a large scar on his right shoulder and tattered clothing when he was in his human form, only for him to become bare-chested and barefoot, leaving only his pants intact.

Abilities
Master Swordsman: Tarco is capable of using dual swords during combat.

Beastification: Tarco, like Garfiel, can use his ancestral Demi-Human blood to transform himself into a tall bipedal grey wolf, almost like a werewolf; with massive and thick limbs as well as razor-sharp fangs and claws which can easily rip a man or even a fully grown earth dragon in two with a single swipe. Tarco's physical strength in his wolf form was increased exponentially. He can also use his swords during this form.
 * Resonance Wave: In this form, he unlocks an ability that unleashes a violent burst of destructive mana from his mouth.

Demi-Human Physique: Tarco demonstrates a variety of enhanced physique and physiology due to his Demi-Human blood.
 * Inhuman strength and speed: Due to his Demi-Human blood, Tarco is extremely strong.
 * Enhanced Sense of Smell: The potency of his sense of smell was also far greater than a regular human's. He can distinguish the scents of separate individuals from a considerable distance.

Trivia

 * Tarco's Alias was "Dog Demon", similar to Wilhelm holding the alias of "Sword Demon".
 * There have been fan theories that Tarco may be a distant relative to either Garfiel or Ricardo due to their similarities in appearances and abilities.
