Which is why I watched the cartoon in the first place when I was little. I never found Gadget himself funny or all that entertaining."
Series Minus Series Core is a kind of work-edition which consist of taking a series and strip it of one (or more) core character(s). Since most series are more-often-than-not character driven, the removal of a key character can change the whole work radically, and that's where the fun of the trope resides.
Think it with the First Law of Metafictional Thermodynamics in mind: if one BIG OBJECT leaves the stage, then plot can progress faster, other characters whose focus might have been diminished may gain greater roles (with new things to explore), and situations might be sweeter or more brutal without our Plucky Comic Relief/Problem Solver.
Characters who suffer from this are always on the main spot, being usually the main character, with roles that range from Plucky Comic Relief (doing something silly every 5 seconds), to Deadpan Snarker (saying something snarky every 5 seconds) to The Ace (solving some problem every 5 seconds). Since they are all very likely to be considered The Scrappy (by at least some of the fandom), these works sometimes (not always) include a huge quota of Take That, Scrappy!.
Works that use this trope as their main premise (organized by medium of original work):
- In 2010, car manufacturer Dodge aired a commercial for their Tent Event that had the announcer (Michael C. Hall) say, "This event could not be more amazing." Then a monkey in a jumpsuit appears and the narrator says, "Oh, wait, there's a monkey." The monkey walks up to a Plunger Detonator and fires off some confetti, and the narrator adds, "I stand corrected." Dodge was contacted by PETA and Chimpanzee Sanctuary Northwest criticizing the use of the monkey in their advert, so they responded with the most tongue-in-cheek way possible: the commercial was re-aired with the monkey removed, leaving just a walking jumpsuit, which the narrator nonchalantly dubs an invisible monkey. The commercial's last line was also changed from, "I stand corrected," to, "Unbelievable," acknowledging how nonsensical the ending had become.
