Richter Belmont is a descendant of Simon Belmont and Juste Belmont. He is a renowned vampire hunter. He is the main protagonist of Castlevania: Rondo of Blood and has reappeared frequently as the supporting character in later games. He has a strong sense of justice and unwavering will. Every generation of the Belmont Clan has produced tougher, more dedicated vampire hunters - yet Richter stands as one of the most powerful in the family. Brandishing the legendary sacred whip which so many of his predecessors wielded, this hot-headed youth pushed Dracula to the brink.
Dracula, resurrected by evil humans who sacrificed a young virgin female's blood and life, commanded his forces to kidnap Richter's girlfriend, Annette, from the village of Aljiba, alongside the villagers, Maria Renard, Tera, and Iris. On his way to the village via wagon, he is ambushed by Dracula's second in command, Death, with the latter also "testing" him by using various attacks on him. After Richter dispelled the attacks, the Death took his leave, although not before vowing that he won't go easy on the vampire hunter in their inevitable next encounter. Richter, obligated to battle the Dark Lord in every incarnation, single-handedly slayed the Count's massive army, including Shaft, and arrived in time to save the women - proving to himself that he was worthy of his vampire-hunting destiny.
Mesmerized by Shaft, who had somehow survived the earlier defeat, Richter betrayed his people and resurrected Dracula: "Dracula rises once a century. One chance for each Belmont to shine, and then we're finished, forgotten. If I bring him back now, the battle can last for eternity!". It was Alucard who arose from his slumber, braved the evil castle, and with Maria's help freed Richter from his delusion. Shaft later revealed that he brainwashed Richter because, due to his status as a Belmont, he was supreme among vampire hunters and thus could not be defeated in a straight up fight between various ones, effectively acting as a deterrent regarding anyone trying to stop Dracula's resurrection.
Richter sends a letter to Maria, warning her about vampire attacks in the village that she and Alucard were staying in, he also tells her to be wary of the vampire.
It wasn't long before Richter tracks down the vampire attacks. There, he encounters Cyril and Alexis, the self-proclaimed vampire hunters. He rescues the two from a skeleton, making himself known.
Later on, Richter rescues Maria, who was hurt by the potion that Cyril made. He brings her back to Alucard, there he tells him that the ones closest to him will be sacrificed once he gives in to his vampiric urges. He advises Alucard to tell Maria why he is letting her stay with him.
On his journey to find the vampire responsible for the attacks, he meets Cyril again. He tells Richter that Alexis had been kidnapped by a black-winged demon. Richter immediately knew it was Magnus and sets out with Cyril to rescue Alexis.
Richter and Cyril finally meet up with Alucard for the final battle against Magnus.
The Vampire Killer is under the ownership of Jonathan Morris, who is unable to use the whip effectively. After Jonathan Morris and Charlotte Aulin cure Loretta and Stella from vampirism, the two sisters offer to aid Jonathan in learning to use the whip's full power.
This is an optional choice, up to the player, and if they choose to do so, the sisters accomplish this by sending Jonathan into another realm to fight the living memory of the last full Belmont to wield the whip - Richter Belmont. Richter fights the player using Daggers, Crosses, Holy Water, Axes, Grand Cross, a fast Dash strike and a fully powered version of the Vampire Killer. Once Richter's illusion is defeated, Jonathan's whip becomes one of the most powerful weapons in the game.
He is reprised by David Vincent in the English dub and he will be voiced by Shinichiro Miki in the Japanese dub as a tribute for Kiyoyuki Yanada.
