Mephistomon

Mephistomon is the true form of KOMPLEX and is an escaped Dark Spawn Lord. He is also the Big Bad of Digimon Tamers Battle of Adventurers.

Reformatted from an Apocalymon, Mephistomon has a deep hatred for all life, and so plots to destroy the world and everything in it. In order to do so, he disguises himself as Ryuuji Tamashiro, the president of the Okinawan VP Laboratories. He soon becomes famous for his part in marketing the V-Pet, a digital pet that he modified to cause other Digimon to Bio-Emerge and become his servants.

Takahito Uehara, the original creator of the V-Pet, detects the virus that Mephistomon had implanted in the V-Pets, and creates a vaccine program which he implants into the original V-Pet, which manifests as Seasarmon. When Mephistomon finds out about the vaccine, he uses his servants to kidnap Takehito and find out the vaccine's location. Once Uehara reveals that the vaccine is in Seasarmon, Mephistomon doffs his disguise and attacks Seasarmon and the Tamers. As part of the battle, he drags the group into an apocalyptic dimension modeled after his intentions for the Real World. Even Mephistomon was stronger the Tamers' digimon (who fought in the their Champion forms), he was defeated by Growlmon blasting a ship floating in the sky, causing it to fall on him, allowing the vaccine program to activate and purge the virus. It is revealed that Mephistomon is not actually dead, and he digivolves to Gulfmon.

Other formsEdit
The name "Mephistomon" refers only to the first Ultimate form of this Digimon. Throughout the series, Mephistomon gains the ability to Digivolve into a number of other forms, each with a different name and special attack. Mephistomon, however, is the form he spends most of his appearance in. {|

ApocalymonEdit
Apocalymon (アポカリモン, Apocalymon?)Added by THBApocalymon attempts to Bio-Emerge in the Real World, but is confronted by Omnimon. During the battle, Apocalymon reformats to Mephistomon. Omnimon attacks him, and even though Mephistomon was no-match for him, Omnimon is unable to stop Mephistomon from Bio-Emerging.

GulfmonEdit
Gulfmon (ガルフモン, Galfmon?)Added by NedBotGulfmon is Mephistomon's larger and more powerful but less intelligent form. The Tamers' Champion Digimon are unable to scratch him, but Calumon's powers activate, digivolving them to Ultimate. As Gulfmon charges at them, they combine their powers into their "Trinity Burst" attack, impaling and destroying Gulfmon.

Role in the series
Mephistomon appeared in the climax of Dave Felis meets Rudolph as the true of KOMPLEX who repeated his EXACT SAME SCHEME from his original movie. Thankfully, Mephistomon was defeated again and reverted back into KOMPLEX. Mephistomon, as KOMPLEX, is the Big Bad of the Dave Felis adventures series, yet has not yet appeared to join his fellow Dark Spawn Lord Big Bads in the Spongebob Adventures Series.
