Psionics involve the use of the mind to alter or command reality, typically through some understanding of a deeper truth about the universe or command over a fundamental law of reality.
It’s pretty cool, but I have trouble thinking of media where it takes a prominent role. The few examples that come to mind are:
Star Wars - The Force Mass Effect - Biotics/Element Zero technology Stellaris - Spiritualist Ethos Warhammer 40k - Psykers/Orks
What are some other examples of psionics in Sci-Fi?
The sci-fi book series “Perry Rhodan” features a lot of humans and other beings with all kind psionic powers.
Telepathy, telekinesis, invisibility, teleportation, fire, ice, atomic restructuring, the list is really really long.
