Mahavairocana Tathagata
In Shingon, Mahavairocana Tathagata (Dainichi Nyorai 大日如來) is the universal or Primordial Buddha that is the basis of all phenomena, present in each and all of them, and not existing independently or externally to them. The goal of Shingon is the realization that one's nature is identical with Mahavairocana, a goal that is achieved through initiation (for ordained followers), meditation and esoteric ritual practices. This realization depends on receiving the secret doctrines of Shingon, transmitted orally to initiates by the school's masters. The "Three Mysteries" of body, speech, and mind participate simultaneously in the subsequent process of revealing one's nature: the body through devotional gestures (mudra) and the use of ritual instruments, speech through sacred formulas (mantra), and mind through meditation.
Shingon places emphasis on the Thirteen Buddhas (十三仏), a grouping of various buddhas and bodhisattvas; however this is purely for lay Buddhist practice and Shingon priests generally make devotions to not just the Thirteen Buddhas.

Mahavairocana is the Universal Principle which underlies all Buddhist teachings, according to Shingon Buddhism, so other Buddhist figures can be thought of as manifestations with certain roles and attributes. Each Buddhist figure is symbolized by its own Sanskrit "seed" letter as well.
