The 'soul' of a Transformer.
* In the transformer mythos, a spark is an orb of pure blue, glowing, oscillating energy. It is essentially a transformer's life force or soul. All such sparks come from a common origin, the "Allspark," which is the life force of the godlike creator Primus. All sparks are mere fragments of the Allspark which sends them to live in the physical world so that they can learn and live and evolve as individuals so that when each spark rejoins the Allspark, the latter can also learn, grow, and evolve.
