Singapore

The economic anchor of Southeast Asia, Singapore is one of the wealthiest cities in the world. It’s ruled by a benevolent sultan who keeps the city clean and orderly using tactics that are fairly progressive by the region’s standards. The trains run on time. The streets are safe and spotless. Street-crusading vigilantes rarely stay in Singapore long: there’s nothing for them to do.
This independent city-state of six million serves as a communications, technology, and transportation hub connecting Australia, Oceania, and Southeast Asia to Europe, India, and the Americas. Because of this, it’s where many supers congregate—or at least lay over—en route to missions in those regions. Outside of Japan, it’s the most likely place for somebody to have a random meeting with multiple heroes or villains.
Singaporean supers are often wealthy scions of local magnates, using their wealth to become gadgeteers or to train their skills to near superhuman levels. Most who join the world stage are at first surprised by how chaotic and dangerous places outside Singapore can be. Those who survive this rude awakening can combine their abilities with their money to become true forces in the superheroic world.
