Aaron Littleton is a hominid that lives roughly 26,000 light years from galactic center. A carbon based life form, Aaron will combust if exposed to temperatures higher than 473 C. A lack of chlorophyll deprives him of the benefits of photosynthesis. Therefore, Aaron both enjoys and requires consumption of plant and meat based nutrients.
Aaron has specific social needs, possibly related to insecurity about his lack of chlorophyll, that cannot be fulfilled without occasionally making a fool of himself in front of an audience. To meet those needs, he joined Einstein Simplified in 2010.
