In What Remains, the Freeks are the mental mutants. Instead of being born with massive muscles, the Freeks are born with big brains. Their brains are big in order to contain their massive psychic powers, including telekinesis and technopathy! That great power comes at a price, because they face the same prejudice and dangers as Mutants and Revenants, so they often hide their powers in order to blend in.
Freeks gain bumps to Intellect & Psychic, plus access to Freek Powers; but they take penalties to Impact and Tenacity.
