Superpotência vs. superpoder
In Portuguese, although both words translate to "superpower" in English, they are used in very different contexts. Superpotência refers to a powerful nation or entity on the global stage, while superpoder refers to a specific ability or talent, usually supernatural or metaphorical.
Superpotência
B2This word is used almost exclusively in geopolitical, economic, or historical contexts. It describes a state, country, or nation with dominant influence and power over the rest of the world. It refers to the entity itself, not an ability.

Superpoder
B1This word refers to a specific skill or ability. It is primarily used in fiction (superheroes, fantasy, sci-fi) to describe supernatural abilities like flying or super strength. It can also be used metaphorically to describe a person's exceptional talent or quality.
