Buddhist mythology overlapped with Hindu mythology. Akshobhya, for example, acquires a fierce Tantric form that is reminiscent of the fierce form of the Hindu god Shiva; in this form he became known by the Buddhist names Heruka, Hevajra, or Samvara. He is known in Japan in this guise as Fudō (“Imperturbable”). The Indian god Bhairava, a fierce bull-headed divinity, was adopted by Tantric Buddhists as Vajrabhairava. Also called Yamantaka (“Slayer of Death”) and identified as the fierce expression of the gentle Manjushri, he was accorded quasi-buddha rank.
