Quite a few, is the shorthand answer. It all depends on who you are counting as Looney Tunes. If you only want the main players, the list is a bit shorter: Bugs Bunny Daffy Duck Porky Pig Sylvester Tweety Granny Elmer Fudd Yosemite Sam Wile E Coyote The Roadrunner Marvin the Martian Pepe le Pew Speedy Gonzales Forhorn Leghorn Tas the Tasmanian Devil So that's fifteen toons on the main list, but there are dozens more on the supporting list, including the cat that Pepe le Pew chases and Porky Pig's girlfriend.
The link below gives you a full list of all the characters, but it also includes the later toons from shows like Animaniancs and Tiny Toon Adventures, which some might not count as official Looney Tunes. http://en.wikipedia.org/wiki/List_of_Looney_Tunes_characters.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
