Curious about Sweet Mask’s true identity in One-Punch Man? The popular A-Class Rank 1 hero is known for his striking appearance and strict views on heroism. But behind the mask lies a deeper story that fans finally uncover in Chapter 211 of the manga.
Here’s what we know about Sweet Mask’s real name, his transformation, and the origin he shares with Saitama during their unexpected conversation.

What’s Sweet Mask’s real name in One-Punch Man Chapter 211?
In One-Punch Man Chapter 211, Sweet Mask reveals his real name, Beaut, during a conversation with Saitama. They are seated together in a gondola when the topic comes up.
Saitama asks why he became a hero. In response, Sweet Mask explains that he struggled with an inferiority complex about his unattractive appearance. To cope, he chose to live by strict moral principles, hoping to be beautiful on the inside.
He joined the Hero Association wearing a mask to conceal his face. As he gained fame and strength, his fear of exposure grew. During a battle, he accidentally broke his mask. Instead of rejecting him, fans cheered him on, noticing his drastically changed appearance. He then realized that his intense self-loathing had transformed his body into that of a Mysterious Being, even though he continued to present himself as human.
The chapter also marks the start of Saitama’s Supreme Hero training. Sweet Mask, aiming to make Saitama more popular, enlists a full team of professionals to assist in a complete makeover. This team includes a fashion coordinator, voice trainer, speech consultant, hairstylist, smile and facial expression advisor, and character designer. He instructs Saitama to get sufficient rest and follow a skincare regimen to prepare for the transformation.
Saitama remains largely indifferent to the effort. When Sweet Mask discovers that Saitama has never seen any of his shows or films, Saitama explains that he only watches free channels. Sweet Mask then reflects that Saitama’s casual approach to heroism may actually embody the essence of a true hero. He cancels the makeover plans and takes Saitama for a walk, during which he reveals his full backstory.
