Belphegor is an assassin working for the Vongola's independent assassination squad, the Varia. He is known as "Prince the Ripper" (Purinzu za Rippa). Once a prince of an unknown country, at age eight he stabbed his identical twin brother, Rasiel, presumably to death. It was later revealed during the Future Arc that this was not the case. Bel has a crescent-shaped birthmark on the right side of his stomach which mirrors Rasiel's. He is known as a battle genius, but his abilities only truly present themselves when he sees his own "royal" blood, which reminds him of the time he stabbed his brother. His eyes are never shown, but in Volume 24, Lussuria says in his interview that his eyes are both cool and loyal.
Belphegor represented the Storm Guardian of the Varia and fought Hayato Gokudera in the Storm Ring Battle. At first Belphegor seemed to have the advantage, confusing Gokudera with his techniques, but he was eventually outwitted. However, spurred on by his instinctive desire to win, Belpegor struggled with Gokudera who (as the area was rigged with explosives) eventually gave up, leaving Belphegor the winner. During the Sky Ring Battle, Bel, like all of the guardians, was incapacitated with a poison. Xanxus gave him the antidote, but Bel was then confronted by Hibari. Bel retreated after injuring him and went to cure Mammon. They proceeded to hold Chrome hostage in order to get the rest of the Vongola Rings from Gokudera and Yamamoto. Mammon and Bel were successful; however, they were disqualified and later surrendered the Rings.
During the main battle in Italy, Belphegor was ordered by Squalo to work with Flan and hunt down the Funeral Wreath in charge. They eventually encountered Olgert and, to Belphegor's surprise, the Funeral Wreath which was his "dead" brother Rasiel, who claimed to have been brought back to life by Byakuran. Rasiel then seemed to incapacitated them. However, it was revealed that Flan used an illusion to fake their deaths so that they could escape.
When Tsuna and company go back to the past for the Arcobaleno Trials, Belphegor and Mammon infiltrate Tsuna's school by using the mist to disguise themselves as the two transfer students, Monta and Himeko Hariyama. This is to help Viper perform his trial. After the trial, he was seen eating sushi at Yamamoto's father's sushi place.
The Varia later arrived to rescue Lal Mirch, Gokudera, and Gamma from the Six Funeral Wreaths. Along with Lussuria and Leviathan, Belphegor was apparently killed by Bluebell. However, this was revealed to be an illusion created by Mukuro Rokudo. Later, Bel, along with everyone else present, had his Dying Will Flames drained by Ghost.
As soon as Tsuna heard Colonnello's voice and saw the Arcobaleno alive, Mammon appeared before them; Belphegor seemed to be happy to see him alive.
He appears briefly with the rest of the Varia at Tsuna's Inheritance Ceremony. When the Shimon launch their attack during the ceremony, he along with the rest of the Varia is imprisoned in spikes of what appear to be ice.

- Visone Tempesta: Storm Mink - Belphegor's Box Weapon, a small Mink with fur that generates Storm Flames that destroy anything it touches. It moves at blinding speeds, making it highly impossible to avoid its deadly attack. It can also produce a Flame shield by rapidly rotating its tail.
