BH Program

The BH Program, short for Brain Hack Program (ブレインハックプログラム, Burein Hakku Puroguramu), is a computer virus that infects Digimon, interfering with their minds and causing abnormal behavior and violent tendencies. It can also forcibly transform infected Digimon into Mugendramon.

The BH Program is responsible for the outbreak of rampaging Mugendramon threatening the Digital World. Mikagura Mirei identifies it after rescuing Takuto/Shiki and their companions from the infected Omegamon Zwart D, the world's Executor. Tests conducted in Floatia reveal that all its residents are infected, although the program's dormant period varies between individuals.

Mameo develops a prototype antivirus that delays the transformation but cannot completely prevent it. His own partner is kept sealed in a Digitama because of the infection.

Nanomon helps optimize the antivirus. However, Titamon broadcasts an enhanced BH Program through Server Tower. This version spreads through the ground as well as the network, prompting Floatia's inhabitants to make the city airborne to escape contamination.

Luche unknowingly carries the source virus in her stuffed Numemon, which also transmits information to Tsuzuki Shoma. Mirei discovers and removes these programs.

Shoma reveals that he created the BH Program to alter the Digital World and its Digimon, converting them into energy for Omegamon Alter-B. This serves his Advanced Realm Plan, which aims to break down the boundaries between parallel worlds. After the antivirus stops Omegamon Alter-B, the protagonists use its purification power in Project Reincarnation to cleanse and restore the Digital World.
