Kadampa/Gedän (Gelugpa) stream has this fellow (Dorje Shugdän) as their Dharma protector:

Dorje Shugdän and the Deities of his mandala are the same nature as the Deities of the body mandala of Lama Losang Tubwang Dorjechang, who is in essence Je Tsongkhapa. After Je Tsongkhapa passed away, Khädrubje received five visions of him, each time appearing in a different aspect. Later, the great Yogi Dharmavajra saw Je Tsongkhapa in the aspect of Lama Losang Tubwang Dorjechang. This name was given to Je Tsongkhapa by Manjushri. It indicates that Je Tsongkhapa is the embodiment of both Conqueror Vajradhara and Buddha Shakyamuni. `Losang Dragpa' is Je Tsongkhapa's ordained name, `Tubwang' or `Powerful Able One' is an epithet of Buddha Shakyamuni, and `Dorjechang' is Tibetan for Vajradhara. Lama Losang Tubwang Dorjechang is an enlightened being and the principal Field for Accumulating Merit in the Guru yoga of Offering to the Spiritual Guide, or Lama Chöpa.

Many sadhanas of Dorje Shugdän state that Dorje Shugdän is the embodiment of the `Guru, Yidam, and Protector'. Here, `Guru' refers specifically to Lama Tsongkhapa. Thus, when we practise the sadhana of Dorje Shugdän we are indirectly practising the Guru yoga of Je Tsongkhapa, as well as the practices of Yamantaka and Kalarupa. Atisha said, `You Tibetans rely upon hundreds of Deities but do not achieve even one attainment, whereas we Indian Buddhists rely upon only one Deity and achieve the attainments and blessings of hundreds of Deities.' We should bear Atisha's comment in mind and realize that it is much more meaningful to practise one Deity sincerely, regarding that Deity as the synthesis of all Deities, than it is to practise many Deities superficially.
Some people believe that Dorje Shugdän is an emanation of Manjushri who shows the aspect of a worldly being, but this is incorrect. Even Dorje Shugdän's form reveals the complete stages of the path of Sutra and Tantra, and such qualities are not possessed by the forms of worldly beings. Dorje Shugdän appears as a fully-ordained monk to show that the practice of pure moral discipline is essential for those who wish to attain enlightenment. In his left hand he holds a heart, which symbolizes great compassion and spontaneous great bliss, the essence of all the stages of the vast path of Sutra and Tantra. His round yellow hat represents the view of Nagarjuna and the wisdom sword in his right hand teaches us to sever ignorance, the root of samsara, with the sharp blade of Nagarjuna's view. This is the essence of all the stages of the profound path of Sutra and Tantra.
Dorje Shugdän rides a snow lion, the symbol of the four fearlessnesses of a Buddha, and has a jewel-spitting mongoose perched on his left arm, symbolizing his power to bestow wealth on those who put their trust in him. The single eye in the centre of his forehead symbolizes his omniscient wisdom which perceives directly and simultaneously all past, present, and future phenomena. His wrathful expression indicates that he destroys ignorance, the real enemy of all living beings, by blessing them with great wisdom; and also that he destroys the obstacles of pure Dharma practitioners.
