The brain. A big, juicy, wrinkled organ on our head that is protected by the skull for a good reason. Now, imagine when it's not...
There are two types of this:
- Just Brain: The brain moves around by itself. It might have some bits attached, such as legs, hovering jets or helicopter rudders, but its main "body" is a brain. Alternatively, it is stationary, and attached to something.
- Acranial Monster: A monster that has its skull being incomplete, thus exposing their brain.
A sister-trope of Brain in a Jar
, although of lot of these brains don't really need the jar life-support system, as well as the furthest extension of My Brain Is Big
Subtrope of Evil Is Visceral
