First incorrect guess was
Twist
Second guess:
Are you are a:
Plot? (ie, a plot twist)
I can keep you grounded, or I can rile you up.
'Plot' as in literally a piece of land, or 'plot' as in a scheme
I can facilitate your travel, or I can discourage you from going.
'Plot' as in a plan of action, or an unexpected incident
a cyborg, a professor, and a statue, schizophrenic mind, and a sled.
All are the main focus of famous plot twists: Blade Runner, ? , Planet of the Apes, Fight Club, Citizen Kane
Hint: As long as people desire entertainment, my forms are seemingly endless.
This fits the 'intangible' def of plot. There are always new stories being made
