Characters whose brains can instinctively or with little effort perform certain complex operations beyond the capability of a normal human mind. This does not necessarily translate into genius as these mental feats are usually automatic and focused to a single trick, having little to do with deliberate cognitive thought. These may be things like an eidetic memory or photographic reflexes. These abilities are more closely related to disorders like synethesia or autism in that they have something to with an abnormal, but beneficial, wiring of the brain.
