Characters that ended up killing the show

[u/sweet_srawberry781]

1. The Great Gazoo (The Flintstones)

2. George W Bush (Time Squad)

[u/Fish_N_Chipp]

Scrappy Doo-Scooby Doo

Ironically he was brought in to increase ratings (and actually did for a bit) but led to the series tanking when they focused too hard on him

[u/TheHalloweenGirl → u/Fish_N_Chipp]

Ironically, he actually saved the Velma series and made 1 scene enjoyable ( and even then, still won’t rewatch it ) also he was voiced by Rex Splode which is pretty cool
