Do not fill this in!==Personality and Traits== ===Stubbornness=== Feeling he and other old people are mistreated and disrespected by others, Marvin is remarkably stubborn and often refuses to budge when he is being patronized or controlled. Though he may sometimes express regret, when he is challenged he will quickly double down and defend his past actions, such as being involved in cutting a deal with [[Manbearpig]]. ===Forgetfulness=== Marvin suffers from Alzheimer's disease and has trouble remembering things, best exemplified by his tendency to refer to his grandson as "Billy." He also confuses his granddaughter's age that she may be a child, and mentions forgetting what his former dog Patches looked like.
