Several images of Dorje Shugden bear a resemblance to Kyabje Pabongka Rinpoche as can be seen here.

Kyabje Pabongka Rinpoche is responsible for bringing this practice to many as he was the Guru of many Gelugpa masters, including H.H. Trijang Rinpoche, who in turn passed Dorje Shugden practice onto his many elite disciples, including H.H. the 14th Dalai Lama.
