The answer
Chapter 539 · updated
Ivankov's hormones, derived from the Horo Horo Fruit, enable him to manipulate human physiology including gender, body temperature, pigment, growth, and tension, allowing him to remake people internally as a self-described human engineer. In New Kama Land, these powers facilitate gender transformations and survival treatments, such as Emporio Healing Hormones to combat Magellan's poison by forcing the body to cling to life through violent convulsions. ch. 538 He also applies Emporio Female Hormones for deliberate sex changes and Emporio Tension Hormones to boost endurance. ch. 537 ch. 539 The effects demonstrate that survival depends on personal will rather than miracles alone. "I basically ate the Horo Horo Fruit and can manipulate hormones: gender, body temperature, pigment, growth and tension." ch. 538, p. 7 "Emporio Female Hormones!!!" ch. 537, p. 13 "Emporio Healing Hormones" ch. 538, p. 2 These abilities underscore New Kama philosophy of freedom beyond gender borders.
