Beelzemon is a Demon Lord Digimon whose name and design are derived from the mythological Beelzebub. One of the "Seven Great Demon Lords", it represents Venus and the sin of Gluttony. While it possesses the power to command the many Demon Digimon, it dares to observe a solitary existence. It is said that it could stand at the peak of the dark army, "Nightmare Soldiers", if it cared to, although it is also said that there exists a Demon Lord Digimon which surpasses even Beelzemon. It possesses its favorite shotguns, "Berenjena" (Esp: "Eggplant"), and rides on the gigantic motorcycle-type machine, "Behemoth". Although its personality is cruel and merciless, it is also exceedingly prideful, so it would never attack the weak. Beelzemon currently serves as a warrior to the Fang Empire, and it is one of the demon lords who joined the Dark Spawn in order to be rewarded with positions of power under Malefor's rule.
Beelzemon appears when Impmon accepts Caturamon's offer. With this new power, Impmon is able to warp digivolve into his Mega form. He is also granted control over a motorcycle that had previous controlled Guilmon. Calumon is the first Digimon he encounters when he briefly stops his motorcycle in front of the fatigued Digimon, however Calumon does not recognize him as Impmon and asks him for help. Despite Calumon's pleading, Beelzemon leaves him behind. Later, he tests out his new abilities on a swarm of Chrysalimon. After obliterating a few dozen, the rest digivolve into Infermon with Calumon's power. However, Beelzemon still defeats it and finally gets the chance to absorb data, before being approached Caturamon who told him now it was his turn to uphold his end of their bargain. He attacks the Tamers, and Renamon is able to recognize him as Impmon. However, the ensuing battle is interrupted by a fierce storm created by the reactivation of the unstable Juggernaut program.
Beelzemon appears again at Digimon Sovereign Zhuqiaomon's Southern Gate to hinder Takato Matsuda and his group. During the following fight, Beelzemon's lust for power quickly overtakes him, causing him to severely injure the Tamers and their Digimon, eventually killing and loading Leomon. Takato goes into a rage, and his hatred dark digivolves WarGrowlmon to Megidramon. At first, Megidramon seems have the upper hand, but when Makuramon appears to berate Beelzemon, he is killed and loaded by Beelzemon, allowing him to defeat Megidramon and even load the Ultimate data of Taomon and Rapidmon.
However, after an epiphany, Takato and Guilmon are able to biomerge and form Gallantmon, who is an even match for the empowered Beelzemon. Nevertheless, Beelzemon soon gets the upper hand again when Caturamon appears to attack Lopmon for her betrayal of the Sovereign. Gallantmon destroys the last of the Devas, but Beelzemon sneaks up and loads Caturamon's data, gloating that the Deva got what he deserved. With this power boost, he nearly slays Gallantmon, until Guardromon distracts him with a Guardian Barrage, and Gallantmon is able to defeat him with a Shield of the Just. As Gallantmon is about to finish him off, he is stopped by Jeri Katou's request that he be spared.
After his merciful reprieve by Jeri's hands, Beelzemon, shocked and seemingly emotionally drained, reflects on the events in his life that led up to that point and wanders off. He aimlessly trudges through the digital wasteland with the image of heartbroken Jeri haunting his mind, devoid of any of his former bloodlust or even the will to live. This left him vulnerable to the revenge of the Chrysalimon he'd previously terrorized, who, upon discovering him, drained him of his energy and left him behind as a beaten and defeated Impmon.
