 Raiden is first depicted as a white-haired adult who uses a protective black-and-blue suit for his missions known as a "Skull Suit" (スカルスーツ, Sukaru Sūtsu). In Metal Gear Solid 4: Guns of the Patriots Raiden has had his entire body below the upper jaw replaced with a prototype cybernetic body; he has also had his blood replaced with a military substitute called "White Blood" (白血, Shiro Chi), which requires regular maintenance. His original cybernetic body is replaced with a black one for Metal Gear Rising: Revengeance that also covers his left eye. Although proficient at all types of weaponry, Raiden specializes in wielding swords which resonate at high frequencies for the last fights in Sons of Liberty and during Guns of the Patriots and Revengeance.
