Tired of his many failures as a super-villain and feeling truly repentant, Heat Wave retired from crime and devoted himself to study with Zhutanian monks. He hoped his religious devotion would cure him of his obsession with fire.
Eventually Heat Wave returned to criminal ways. It is unclear to what extent he retained the religious beliefs and practices he adopted while studying with the Zhutanian monks.
Presumably Zhutanian religion is a form of Tibetan Buddhism, but we need to do further research on this in order to verify this assumption. One can guess that "Zhutanian" is a word derived "Bhutanian." The state religion of Bhutan is Vajrayana Buddhism, i.e., "Tibetan Buddhism."
