Even though there is life, no one here is living it. Life is overflowing from you and these people are merely drinking their fill, but Dio and all the people I've met on my journey aren't like that...they're..they're more...they were blazing with fire...they were torches burning with life.

Casshern (キャシャーン Kyashān) was a robot created by Braiking Boss' top scientist Ohji in order to pro-create robotic life. His purpose was a failure, so he was utilized as a perfect killing machine for Braiking Boss. He was originally partnered with his twins Dio and Leda but stayed offwards and was chosen to be the strongest amongst his siblings. Because Casshern was so powerful he was tasked with eliminating Braiking Boss' most illustrious enemy Luna.

Casshern assassinated Luna and mixed his blood of death with hers of life, causing the entire world to spin into a cataclysmic state known as the "Ruin." This also caused Casshern to lose his memory which led him to wander the planet known as Casshern, the Man Who Slayed the Sun that was Named Moon.

While wandering the planet, Casshern met several enemies and companions who helped him learn of his past and ways to atone for his sins. Casshern would soon find that Luna was reborn as a goddess of false life, and that Casshern's new purpose was to bring true life to the world by showing them the reality of death.

Physical Appearance

Casshern was built in a humanoid shape, identical to Dio in features such as their height, weight and structure. He is also completely unaffected by the Ruin, making him look unstained and perfect. He is constantly referred to as "beautiful" due to this.[1][2]

He has a clear appearance that would match that of a human; large fluffy brown hair and soulful blue eyes. He is quite tall with long, muscular limbs all covered by his full body white, skin tight suit. The suit is designed with black lines and a unique "C" on his chest.

The suit also sports a large collar and two jet boosters on the hips. Casshern also has a battle helmet that matches his suit along with earpieces that are similar to his jets. The final pieces of the helmet include the forehead horns that were symmetrical until Dio shattered one of them in battle[3], and also the helmet's retractable mask.


Casshern was originally a merciless being without any sense of reason or morality.[4] When he murdered Luna he quite literally passed this trait onto the world, murdering it and making it a world with no morals or reason. After his rebirth, Casshern became a calm, naive boy who had to learn about his past from enemies and allies alike. As he learned he was constantly ridiculed for who he once was, forcing Casshern into a depression.[4]

Despite his darkness, Casshern still wished to atone for what he had once done and looked for people throughout the world who he had not completely destroyed. These people helped Casshern realize what the world once was and allowed him to strive to stop the Ruin due to their inspiration. Although Casshern had the will to do good, it was still in his nature to be a ruthless tyrant, and this rage would both keep Casshern from sacrificing himself and force him to murder and defend himself.

But when others such as Dio and Braiking Boss remind Casshern of who he was from their perspective, it commonly causes him to become suicidal due to the mental trauma of the surprising realization of his past.[4]Although this suicide was only to help the world, Casshern found another way to do so by seeking out Luna.[5]

By finding Luna, Casshern finally realized who he was; Death. Casshern sacrificed his pride and whatever future he had to become the world's death so that everyone could truly live. This proved that Casshern really was a selfless man who had come from an astonishing change.[6]

He can move fast enough so that he appears to warp-he is also very agile and can perform various acrobatic maneuvers.

Casshern is durable, able to take powerful blows as well as slashes and stabs and continue fighting. Randomly during battle, Casshern enters a berserker state in which he performs to the fullest of his abilities and does not stop or hold back until his enemies are destroyed. He seems to enter this when his life is in serious danger, after a prolonged amount of time fighting, or when angry. While in berserker mode, his eyes glow a bright white He somehow holds the ability to painfully regenerate from any injury and goes violently berserk when incited. In one instance, he was impaled in three different areas before defeating his opponents. He has a healing factor, which activates after a delay. It heals any wounds in moments, and appears to cause serious pain to Casshern. He has healed from dozens of slash wounds, and once was impaled completely through his chest.
