The Vajradhara Rakshasa is an enemy in Crisis Core -Final Fantasy VII-.
The beast has an unavoidable Quake-like attack called "Magnitude 8" which is able to inflict ~1,000 points of HP damage. Be sure to cast Regen and Wall at the start of the battle, followed by a barrage of Graviga towards the Rakshasa. When its HP is low enough, switch over to Hell Thundaga until it is defeated.
Vajradhara is the ultimate primordial Buddha, or Adi Buddha, according to the Gelug and Kagyu schools of Tibetan Buddhism. Achieving the 'state of Vajradhara' is synonymous with complete realisation.
Rakshasa are gigantic demons from Hindu and Buddhist mythology. They are powerful beings aligned with evil, who live on human flesh and spoiled food. The creatures make an important appearance in the epic of Ramayana.
