Gompo Bernagchen: The two-armed "Black-Cloaked Mahākāla" is a protector of the Karma Kagyu school clad in the cloak of a māntrika "warlock". His imagery derives from terma of the Nyingma school and was adopted by the Karma Kagyü during the time of Karma Pakshi, 2nd Karmapa Lama. He is often thought to be the primary protector, but he is in fact the main protector of the Karmapas specifically.
