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 (滅却師 (クインシー)の父, Kuinshī no Chichi) and the emperor of the Wandenreich, with the designation "A" - "The Almighty". He is the son of the Soul King.

Credit to Nefisnef, I used his Yhwach model as a base and changed it which is linked here:
