The Professional Superhero
You basically have being a superhero for a paying job, which can be useful because it generally expedites saving the world and making it a better place - you’re legally authorized to do things you wouldn’t be otherwise. Also, you get a steady paycheck for your efforts. Examples of professional superheroes in fiction include many employees of SHIELD and members of the Green Lantern Corps.
The Pros:
Steady paycheck, employers will (hopefully) cover medical and supply costs. You'll also be authorized to legally carry out actions that you would otherwise have to make sure you didn't get caught doing if you went indie.
The Cons:
Professional superheroes are often limited in terms of what they can get away with and have significantly less personal freedom, similar to working conditions in military or paramilitary organizations. You do not have free reign over your actions, do not get to choose what missions or deployments you’re going to be sent on, and because you’re a part of the system, your actions will be seen as representative of your organization. If you work for an organization that’s public knowledge, that alone can be a lot of responsibility in addition to the moral responsibility of having superpowers, and this could mean getting in a lot of trouble if you do something that damages your organization’s reputation - and remember, you can still end up in trouble even off-duty. If your organization is supposed to be secret, you can also bet that you’ll have to work just as hard, if not harder to prevent your organization from being exposed.
