Here are the key steps to creating your own fictional hero:
1. Decide on gender, age and whether to base them on real people. This will shape their personality and backstory.
2. Determine how they obtain powers/abilities - innate gifts, scientific accident, supernatural means etc. Their origins influence their worldview and motivation.
3. Choose a role - superhero, vigilante, antihero etc. This defines their methods and moral code when facing challenges.
4. Design a signature look with costume/disguise elements if a public figure. Visuals help establish their brand and what they represent.
5. Craft a backstory covering origins, education/occupation, relationships and personality.
