Jonathan Morris is the son of John Morris and as a hunter his direct successor. While Jonathan was a hot-headed and energetic young man, he had to him a confidence, a certain poise, and a sense of humor in the face of even the greatest adversity. Due to this disposition, he was at times viewed as aloof and perhaps not taking important matters too seriously. His most common response "No problem," John was in contrast quite clever when it really counted. Maybe it was his nature. Or maybe he was perhaps compensating for the loss of his father, who died as a result of overuse of the Vampire Killer, which if not utilized sparingly brings about dire consequences for any non-Belmont successor to wield it. With this knowledge, his wounds suffered during the battle with Dracula failing to heal, John didn't train his son to use the Vampire Killer and instead hoped for his son to develop strength enough to survive using other means. Jonathan, who was thus unable to unlock the whip's power, always viewed this as a shirking of responsibility, an incomplete training, and came to resent his father, who in his eyes "ran off and got himself killed." He would slowly learn the truth during his future adventure.

It was Jonathan Morris and childhood friend Charlotte Aulin who answered the call when Castlevania mysteriously rose from the depths and the Church called for its investigation. They raced to the castle and together discovered the source of its rising: The vampire Brauner had harvested the souls of those felled during World War II and had used their collective force to raise from the depths the feared castle, whose power he would harness to extract revenge against the humans on behalf of his daughters, who because of their actions died during the previous world war and seemingly lived on as vampires. Without the whip, Jonathan thought, there was little hope, a feeling the antagonists used to belittle the young hero. A source of encouragement and great assistance was Wind (Eric Lecarde's ghostly alias), who provided information that when put to use was instrumental in the heroes' foiling of Brauner's plans. They were with his help able to deduce how Dracula's power was being suppressed; they were able to save Stella and Loretta, Eric's daughters who Brauner had in reality stolen from him, and spare them eternal suffering; and they learned the truth about John Morris' death--a discovery that instilled in John a newfound respect and a drive to duplicate his father's efforts.

Thanks to Stella and Loretta, living members of the Lecarde family, Jonathan was able to unlock the power of the Vampire Killer by defeating the Whip's Memory--an image of the last Belmont hero to wield the whip. In defeating the image of Richter Belmont, Jonathan could now command the ultimate weapon against evil with the price being part of his life; this reality apparent, he knew well, as did his allies, that the whip should be used only when necessary and at final battle's closure locked away so that he would not suffer his father's fate. A finale so epic could only be fought against one such as Dracula, whose power not even Brauner could contain. Jonathan, honoring his father's teachings and a promise to Eric, showcased his strength and overcame the Dark Lord with a face of responsibility and bravery.
