I suggest splitting the original post into two sections: one for Cartoon Network original shows and another for Cartoon Network acquired shows.
Original Shows:
[Show spoiler]Adventure Time, The Amazing World of Gumball, Ben 10 and sequels, Camp Lazlo, Class of 3000, Courage the Cowardly Dog, Cow & Chicken, Craig of the Creek, Dexter's Laboratory, Ed Edd n Eddy, Foster's Home for Imaginary Friends, The Grim Adventures of Billy & Mandy, I Am Weasel, Infinity Train, Johnny Bravo, The Life and Times of Juniper Lee, My Gym Partner's a Monkey, OK K.O.! Let's Be Heroes, Over the Garden Wall, The Powerpuff Girls + reboot, Regular Show, Samurai Jack, The Secret Saturdays, Star Wars: Clone Wars, Steven Universe, Summer Camp Island, Sym-Bionic Titan,We Bare Bears
I believe everything else on the list is an acquired show... yes, including Johnny Test haha
