Do-S

**Do-S** (also known as Monster Princess Do-S or Super S) is a Demon-level Mysterious Being and member of the Monster Association in *One-Punch Man*. She has a sadistic, arrogant, and highly dominant personality that perfectly matches her dominatrix aesthetic. She revels in controlling others, treating her victims like toys or devoted “love slaves,” and expects absolute obedience. She carries herself with a princess-like superiority and takes clear pleasure in breaking people’s wills through pain and humiliation. Her main ability is her spiked whip, which delivers both physical damage and powerful hypnotic mind control. Anyone struck by it can be turned into a love slave (marked by heart-shaped pupils) who obeys her every command until she is knocked out or willingly releases them. Strong-willed individuals can resist the effect. She also has enhanced strength, speed, and durability for a Demon-level threat, a long prehensile tongue, and once used a dog whistle to summon the Dragon-level monster Overgrown Rover. In the series she primarily acts as a field operative for the Monster Association, attacking heroes and civilians alike to swell the ranks of her controlled slaves. She first appears during the Monster Raid, easily defeating and brainwashing lower-ranked heroes and most of the Blizzard Group. Later she tries to claim Sweet Mask as her 1,000th love slave and clashes with various heroes before ultimately being defeated.
