A personality component is a part of a Transformer's anatomy that governs their personality and without which they would be a dumb, almost zombie-like mechanoid. Personality components can be removed and replaced safely. Some criminals are imprisoned by storing their personality components in a detention center, where for some reason they resemble energon cubes. Note: It's not really known how this relates to the concept of Sparks, though the existence of shell programs would imply that personality is to a degree independent of an individual's Spark.
