He was formed from the postive energy of children when Taichi Yagami & Yamato Ishida both digitalized into the computer world so that they could help their Digimon stop Diaborromon. This incident

Second Season (Digimon 02): Diaborromon's Revenge
Three years later, when Diaboromon was discovered to have survived, Omnimon went to 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 Coup De Grace with his Transcendent Sword destroying Diaboromon, but it was all a trap for all of the Kuramon to get through to the real world which then formed Armageddemon. Omnimon was able to follow to the real world as well to deal with Armageddemon but despite his best efforts Omnimon was no match for him and his arms were seperated from his body. In the end Omnimon gives the rest of his energy to Imperial Dramon Fighter Mode creating Imperial Dramon Paladin Mode where his main body transforms into the Omega Sword (Omega Blade) while the arms revert back to Agumon and Gabumon.

He is the confident leader of the Royal Knights. He's a follower of the word of Yggdrasil, a super-digital being. But it took Alphamon's saving Omnimon's life{Giving Omnimon his X-Antibody to X-Evolve} to open the knight's eyes & see Yggdrasil as it really was. He destoryed Yggdrasil, resetting the Digital World as a result.
