Please tell me some anime (action/mystery/etc stuff, not slice of life) that is not an adaptation of a manga or anything, stuff that was an anime before it was anything else. I already know a bunch, but I'm trying to dig up as many as I can cause I don't like watching adaptations.

I already know:
>Aquarion
>Big O
>Code Geass
>Cowboy Bebop
>Darker Than Black
>Ergo Proxy
>Eureka Seven
>Gun X Sword
>TTGL
>Kill la Kill
>NGE
>Psycho-Pass
>Samurai Champloo
>Witch Hunter Robin
