Omega Rugal/Story

The King of Fighters '95
See also: Rugal Bernstein/Story.

When Rugal Bernstein was trying to channel Orochi's power, Goenitz came to him and attacked him, removing his eye permanently. Rugal survived the attack and Goenitz gave him some extent of power and warned him not to use his full power. Goenitz left Mature and Vice to watch him. In '94, Rugal sponsored the King of Fighters tournament but lost to Kyo Kusanagi. He returned the following year and decided to use 80% of his full power, causing his hair to turn white with his skin gaining a darkened-pale complexion.

Even with that power and his cybernetic enhancements, Rugal lost to Kyo, Benimaru Nikaido and Goro Daimon. Frustrated by his 2nd defeat, Rugal tries to tap in more of the Orochi power, but just as he does, Rugal's body explodes into microscopic pieces, instantly killing him.

Omega Rugal returns in The King of Fighters 2002 (and its remake, The King of Fighters 2002 Unlimited Match), now in a new airship. He goes all out from the start, with powerful attacks and skills. Despite this, he is defeated by whichever team came his way, with him dying after the airship explodes (in KOF2002) or him blowing it up with himself (in KOF2002UM). He seems to be gone for good this time...
