A human being, who has extreme characteristics, such as high intelligence, athleticism, strength, extreme perseverance, non-worldly, idealistic viewpoints, and a hard-nosed, hard-working attitude. His prioritization skills are magnificent. But on the opposite end of such characteristics, he tends to be gullible, awkward, and easily disappointed by the society that surrounds him due to its materialistic approach to life and its willingness to give up. This separates him from society, which, while he still can obtain and maintain friendships, views him as a mongrel of competitive nature and a threat to their own well-being.
