Depends on the time era.
For when I was young, Danny Phantom and Hey Arnold.
A bit older, Samurai Jack, Fullmetal Alchemist, and Courage the Cowardly dog.
Right now, all of the above, and now including Gravity Falls, the Amazing World of Gumball, One Punch Man, Matlock, Monk, Who's Line is it Anyway?, and perhaps a bit more that I've yet to include.
I'm currently looking forward to the new Series of Unfortunate Events show on Netflix, and my fandoms include
most things Nintendo, Undertale, the Phoenix Wright series... and One Piece.
