Maurice, Sheldon and Lydia use their wheelchair (referred to as "Gentitron"), walker (referred to as "Sahpilator") and walking stick (referred to as "Grandmachine"), respectively, as equipment in battle. In their older forms, they can combine these three devices to create a small mech called "Senior Citizen".
While the Senior Citizen Squad don't particularly like the KND, they are mostly concerned with their personal affairs like eating tapioca and use their abilities in villainous ways towards that end rather than to destroy the Kids Next Door. However, their teenage forms were seen at Mr. Boss' Annual "We Hate the Kids Next Door" barbecue in Operation A.F.L.O.A.T.
In Operation L.U.N.C.H, Lydia, Sheldon and Maurice spring into action as the Senior Citizen Squad to beat up Robin Food after he gives them unwanted junk food stolen from kids' lunches. They last appeared in Operation: I.N.T.E.R.V.I.E.W.S., where they came to the amusement park to get the Delightful Children's cake, but decided to leave when they heard they had to do a scavenger hunt, while all the villains decided to play.
