A recurring boss from SNK's The King of Fighters. A wealthy arms dealer, Rugal ran afoul of Goenitz and lost an eye during a battle with him. Impressed by Rugal's ruthlessness, Goenitz shared a fraction of the Orochi power with him, greatly amplifying his strength. Rugal replaced his right eye with a cybernetic orb, which restored his sight to some degree.
He hosted the 1994 King of Fighters tournament, serving as the game's final opponent. The battle with Rugal takes place on his private aircraft carrier, the Black Noah. In several games from the series Rugal appears as an enhanced form named Omega Rugal.
- He is the originator of the Genocide Cutter
- He has two children named Adelheid and Rose.
- In Capcom vs SNK 2, he gets another alternate form called God Rugal.
- He's often paired up with Touhou's Yakumo Yukari.
- Artist Houtengeki does artwork of Touhou's Fujiwara no Mokou cosplaying as Rugal.
