Death

"Oh wow. Look at that. It's Death, also known as the Grim Reaper. I remember this guy. He's one of the Four Horsemen of the Apocalypse when World War III began. Now I'm seeing this guy again... if he threatens us, we would fight him back... I bet."

--Su Ji-Hoon, The Lost Horseman of the Apocalypse

Death, also known as the Grim Reaper, is a major villain from Konami's Castlevania series. He is a being born out of Chaos, which in turn came about from the evil in the hearts of humans. Death is Dracula's right hand man, thus he usually appears near the end of the protagonist's quest, often in the Clock Tower, to challenge them before they confront Dracula. He is also sometimes the first of Dracula's major servants to greet the protagonist, such as in Castlevania: Rondo of Blood, Castlevania: Symphony of the Night, and Castlevania: The Arcade. He has appeared in every game except Castlevania: The Adventure and Castlevania II: Belmont's Revenge.

In When the Cold Breeze Blows Away, he is the right-hand man of the Dark Lord Knight. Before that, while riding on the horse with the fellow Four Horsemen of the Apocalypse, Famine, War, and Conquest (in which he would later be replaced by Pestilence), he fell down after he whipped too much on his horse, and fell down to the Carpathian Mountains, then he served Dark Weiss.

When Dark Weiss has been killed, and with Death being defeated, and the Dark Lord Knight having Dracula's power into a true Dracula like Gabriel Belmont, Death always promise that he has to obey him and help him to join by his request, then the Dark Lord Knight accepted his request join him, and Death will be new supporter of Dark Lord Knight when Dark Lord Knight became the true Dracula when he took Dark Weiss' power to prepare to fight Dracula, and have revenge on the new Four Horsemen of the Apocalypse, Famine, War, Conquest, and Pestilence.

He will fight for Dark Lord Knight and Yang when the Dark Lord Knight, wearing Dracula's tunic and becoming Dracula by the time when Dark Lord Knight took Dark Weiss' power. After defeating the Four Horsemen of the Apocalypse for his redemption, he will fight for Grand Alliance, Su Ji-Hoon, the Preschool Girls, the Sonic Alliance, all the allied teams of Team RWBY and Dark Lord Knight when Dark Lord Knight became the true Dracula.
