Janitor (Scooby-Doo and Guess Who?)

The evil and unnamd Janitor

The unnamed Janitor (Grey DeLisle) is the main villainess from "When Urkel-Bots Go Bad!," episode 1.07 of Scooby-Doo and Guess Who (airdate August 15, 2019). She is a janitor at a Chicago-based museum.

The episode featured Mystery Inc. being encountered by Steve Urkel (of Family Matters fame), as his Urkel-Bot went haywire yet again. He enlisted the gang's help regarding Urkel-Bot, which led him to the aforementioned museum, where after encountering the director, a security guard, and a lunch lady (all of whom despised Urkel and wanted vengeance on him) they met the aforementioned janitor, who greeted Urkel warmly and was grateful for his accidents keeping her employed.

In addition, the gang also ended up dealing with a monster known as The Technomancer, who had the ability to control robots. After a clue led to a legend involving a WWII-submarine and a missing shipment of gold, the director became the group's main suspect, leading to the gang planning to trap the Technomancer. Urkel unleashed the Urkel-Bot 2.0, whose nerdiness baffled the robot henchmen, and regarding the Technomancer, Urkel-Bot ended up capturing the creature, who was revealed as the female janitor.

As Velma revealed, while the janitor was cleaning the submarine, she scratched the paint and discovered that the parts were made of gold. The villainess decided to take the gold for herself, operating the bots to take the gold pieces and melt them into bars, which she could smuggle in her truck--after which she replaced the gold parts with plastic ones. The evil janitor lambasted the gang and Urkel for foiling her plans, and as she was being taken away and arrested, Urkel asked her about the Urkel-Bot going haywire, with the villainess stating that the bot went haywire because it was based on Urkel himself, revealing her own antipathy towards Urkel.
