Cyberse (サイバース Saibāsu) is a Type of monster. This Type is used by Yusaku Fujiki and Revolver in Yu-Gi-Oh! VRAINS. Appearance-wise, they resemble creatures and humanoids strongly connected to elements of digital technology and cyberspace. At times, they tend to resemble either Machine, Insect or Psychic monsters (the humanoids bearing design elements from the TRON franchise). The name is a portmanteau of "Cyber" (サイバー Saibā) and "Universe" (ユニバース Yunibāsu).
