is a character in the
Digimon series and is one of the Thirteen
Royal Knights . He was known as '''Omegamon''' in the Japanese version, and is the result of a fusion between WarGreymon and MetalGarurumon. The head of each became fused onto Omnimon's arms, enabling him to use two attacks: Transcendent Sword (Grey Sword in Japan) with the WarGreymon arm, and Supreme Cannon (Garuru Cannon in Japan) with the MetalGarurumon arm.
When WarGreymon and MetalGarurumon DNA Digivolve, their heads become Omnimon's left and right hand respectively. When X-modified by the
X-Antibody , he becomes
Omnimon X .
- Slashes enemies with his sword from WarGreymon's mouth.
- Shoots energy balls from his cannon from MetalGarurumon's mouth.
Omnimon was formed from the energy of
Tai and
Matt when their respective Digimon proved unresponsive in the Digital World. Both Tai and Matt digitalized into the computer world by accident, and helped their Digimon fuse into Omnimon to defeat
Diaboromon .
Izzy redirected thousands of other children's supportive emails at Diaboromon to give him massive lag, and Omnimon was able to defeat him and deactivate the nuclear missiles Diaboromon had hacked into and sent to Japan.
Three years later, when Diaboromon was discovered to have survived, Omnimon went into the Internet to deal with him once again. With some help from
Angemon and
Angewomon , who helped distract Diaboromon and hold him down, Omnimon was able to administer the final blow with his Transcendent Sword, essentially destroying Diaboromon, but it was a trap for all of the
Kuramon to get through to the real world. The Kuramon formed
Armageddemon , and Omnimon was able to follow it the real world to deal with it, but because he used up too much of his energy coming back to the real world, Omnimon was no match for Armageddemon at his full strength. During the battle Omnimon's arms were separated from his body and in the end Omnimon gave the rest of his energy to
Imperialdramon Fighter Mode , creating
Imperialdramon Paladin Mode , where his main body transformed into the Omni Sword (Omega Blade in Japan) while the arms reverted back to Agumon and Gabumon.
Omnimon later appeared in a fifth Digimon movie. This Omnimon opposed the Digimon
Mephistomon , who was spawned from the data of an
Apocalymon . Unfortunately, Omnimon failed to stop him, and had to assemble
Takato ,
Rika and
Henry to fight Mephistomon for him when the evil Digimon escaped into the real world of the
Digimon Tamers universe. Omnimon was unable to emerge into the real world himself.
It is unclear if this Omnimon was an inhabitant of the Tamers Digital World or not, but an Japanese option card that was released in conjunction with his movie appearance was given the name of "The Dimension Crossing Hero", which implies that he and Mephistomon existed outside of the Tamers universe.
This Omnimon referred to the Tamers as
DigiDestined in the dub, as a throwback to the older seasons.
Omnimon is the third Mega Digimon
Zeromaru had to fight, the partner of
Hideto Fujimoto of the Alias Three, made up of Org the WarGreymon and Meruga the MetalGarurumon. After being defeated by Zeromaru, Omnimon would later help him out in the fight against
Arcadimon . He is the only Digimon of the Alias Three that was not destroyed.
He is the confident leader of the
Royal Knights , initially carrying out Project Ark almost to the letter. He is a follower of
Yggdrasil , a super-computer governing the current
Digital World . In X-Evolution, he is the main policing power, although he acts against informants and those betrayed with unprejudiced force. When
Gallantmon confronted him about Yggdrasil, they were unable to agree about the nature of Project Ark and so they fought, ending with the other Knight's demise. This event is what made Omnimon seriously start to question Yggdrasil, shaken as he is by his friend's death. But even so, he still carried out Yggdrasil's orders. It was only when
Alphamon saved Omnimon's life and gave him an
X-Antibody that the Knight's eyes were really opened to Yggdrasil's true motives. Transforming into
Omnimon X , he destroyed Yggdrasil with All Delete, resetting the Digital World as a result.
