The Elderly Man (real name unknown) is a senior among the adult characters. He is voiced by Phil LaMarr.
He is seen in Immune to All But Justice, at a park feeding bird seed to some doves. When Fillmore and Ingrid are chasing after Lumberjack through the park, Lumberjack takes the Elderly Man's bag of bird seeds to dump it on the Safety Patrollers in an attempt to evade them. The doves then fly over to them and eat the seeds off of them. The Elderly Man tells them not to bother Ingrid.
