Guts is the protagonist of the dark fantasy manga and anime series 'Berserk'. Known for his formidable strength and swordsmanship, Guts is a brooding and intense figure who is relentlessly pursued by a curse known as the 'Eclipse'. He harbors a traumatic past and is often driven by a desire for revenge and a fear of abandonment. Despite his hard exterior, Guts has a soft spot for children, particularly his adoptive sister, Casca, and his trusty sword, Dragonslayer. He frequently butts heads with his comrade and rival, Puck, a small, green, and mischievous fairy-like being. His aloofness and struggle with the darkness within him often set him apart from others, making him a tragic yet captivating anti-hero.

Yami Yugi, known as Atem in his ancient Egyptian form, is the central character in the Yu-Gi-Oh! series. His kind, calm demeanor contrasts with his unparalleled skill in the card game Duel Monsters, underlined by his stoic and mysterious past. As Yami Yugi, he dons a golden mask and represents the spirit of the legendary Egyptian pharaoh who ruled thousands of years ago. He values truth and integrity, fighting for justice and fairness with a mature sense of responsibility. Atem, his counterpart, is often depicted as more boyish and playful. He is deeply connected with his friends, especially Anzu Mazaki, whom he has a protective instinct towards, and Joey Wheeler, with whom he shares a friendly rivalry. His opponents range from the formidable Seto Kaiba to various characters from the Shadow Games world. Though seemingly soft-spoken, Yami Yugi shows ferocity when required, especially when protecting the innocent or when dueling for the sake of what he believes in.
