- Robin, thank you so much for helping with our Senior Center!
- --- Small Senior Lady
The Seniors are a group of minor characters. They appear as extras and background characters in several episodes, but are featured prominently in the episode "Hey Pizza!".
As the source of Robin's conflict, he had to decide whether to build a senior center for them (especially since they deserve it) or build a community pool so he can see Starfire in a bikini. They are friendly to the Titans, having brought them cookies and made Robin a new suit (a knitted, pink, pajama-like reconstruction of Robin's suit complete with narwhal slippers) with their arthritic hands.
- The small senior lady with tiny, pink glasses in the group has a similar voice to Truffles in Chowder. This is probably due to Tara Strong voicing Truffles in that series.
- The suit made by the old seniors is shown hanging in Robin's closet in "Staff Meeting".
- The male senior looks like Mumbo Jumbo's human form from the original Teen Titans.
