A 'Pretender'; a super-genius polymath with eidetic and working memory (possibly Hyperthymesia), who has the ability to be anyone, learn any skill and function in any situation – a chameleon who takes on identities as easily as most people change clothes. It is revealed at the climax of the second season that due to being of a rare genealogy, Jarod is genetically dispositioned to being a "Pretender", as are a rare few, but Jarod's is more pronounced. According to "The Pretender: Rebirth", Jarod uses about 20% of his brain, while most people use about 10%. It is also revealed near the end of season 2 that Jarod and his brother, Kyle, share a rare blood type, AB- blood. It is mentioned twice in season 4 ("Risque Business" & "Cold Dick"), that Jarod has a pistachio allergy. Since at least the time from when he was abducted, he has known the couplet "Kri Kra Toad's Foot, Geese Walk Bare-foot" (which is the English translation of the German couplet "Kri Kra Kroten-Fuss, Gänse Laufen Bar-Fuss").
