Yhwach (ユーハバッハ, Yūhabahha), often referred to simply as “Your Majesty” (陛下, heika) by his underlings, is the Father of the Quincy and the emperor of the Wandenreich, with the designation “A” – “The Almighty”. He is the son of the Soul King.

Yhwach is a tall man with a long face, broad chin, and pronounced cheekbones. He has long black hair, which reaches to his lower back, and reddish-brown eyes with thin eyebrows. He has well-kept mutton chops and a connected mustache, but is otherwise clean-shaven. His usual attire consists of a white, double-breasted trench coat, which has the Wandenreich symbol on the middle, with large buttoned cuffs and lapels, white trousers, and trench boots. Over this, he wears a tattered, ankle-length maroon-black cloak, which has a red ribbon near the neck and is fastened to the left with a single large button.

As noted by Ōetsu Nimaiya, the manifestation of Ichigo’s Quincy powers heavily resembles Yhwach’s appearance from 1,000 years ago; similarly, the Bankai form of this manifestation looks like Yhwach when he was in his teenage years. During the Wandenreich’s second invasion, his maroon-black cloak is replaced with a white version. After absorbing Mimihagi’s powers, Yhwach gains a black pattern of eyes running down the left side of his face and onto his chest, and his left eye becomes inverted in coloration.
