What's your favorite childhood cartoon?

Pinky and the Brain.
Although now as a middle aged man, Bluey.
- Bluey is GOAT level.

Wtf no one said TOM&JERRY??
- The background art in the early ones was beautiful.
- I was about to type about tom and jerry lmao
- I used to watch a lot of Boomerang in Latin America, they aired either OG Looney Tunes or Tom and Jerry for 1 hour daily
- I had a love/hate relationship with that show because I felt so sorry for Tom. Kept watching it though so clearly it did something right.

Ed, Edd, and Eddie
Courage the Cowardly Dog
- Pluto TV is missing out in not making a deal with whoever the owner of CN is, those classics deserve their spot there...
  In the meantime I am happily using DizqueTV to make my own channels 😂
  
  Adult Swim has Checkered Past, and they air Courage and Ed, Edd and Eddy
  They also air Billy and Mandy and What a Cartoon as well

The Tick.
I really enjoyed the comic book hero shows, and The Tick and Freakazoid were great fun to watch as parodies of the genre.
I was so happy to see The Tick get a couple of seasons as an Amazon show.
- I'll throw in EEK! The Cat in with the hilarious and witty parodies

People have already mentioned SpongeBob, so I will go with Freakazoid and The Tick.

Static Shock, Kim Possible, Darkwing Duck

SpongeBob. The early seasons were and still are god-tier

Invader zim

Basically any fantasy cartoon that featured a voyage or some kind of quest was a favorite when I was little.
The Adventures of Teddy Ruxpin
Dungeons & Dragons
Pirates of Dark Water
Conan the Adventurer
- Dungeons & Dragons is such a classic. I still watch it on occasion.
- Pirates of Dark Water was such an underrated show. It still makes me mad that it got canceled.
- The opening theme to Tintin is playing in my head right now. What a beautiful cartoon.

This shouldn't be the answer because it's not really for kids. But it is, and will always be, The Simpsons.
Every evening at 6pm on UPN I would watch the Simpsons with my dad. I went from watching and understanding Bart to now watching with my daughter and seeing it through Homer's eyes.
- As a kid, I would always flip on the TV for the evening episode of the Simpsons too haha! Except I swear for me it was 5pm.
  
  I'm EST. Maybe you are central time? Bill Nye was on at 5pm on PBS for me

Then or now?
5 year old me: She-Ra
10 year old me: maybe Bugs Bunny honestly
Adult me: Bluey hands down forever. And my kids like it too.
- The new she-ra is rad.
  
  totally

Robotech

Jem and the Holograms
Danger Mouse
The Smurfs
The Snorks
The Jetsons
David the Gnome
Marsupilami
- Came here to say David the Gnome, just rewatched it recently and loved it. Never met someone else in real life who has ever seen it.

Gargoyles, Batman The Animated Series, X-Men, Exosquad, Animaniacs, Pinky and the Brain. Liked them equally.
- I would have never memorized the presidents without Yakko, Wakko and Dot
  
  Heck yeah! Great rhymes.

Starblazers

Goof Troop
TaleSpin

Not my favourite but I'm throwing this out tbere.
Gargoyles

Saber Rider and the star sherrifs
- Galaxy rangers

Arabian Nights. The adventures, Jeenie, Magic carpet, Abu, and everything was awesome.

I have a soft spot for Hey Arnold! and Rugrats... If I had to pick one from another but Nick that would be Courage The Cowardly Dog.

Tiny Toon Adventures, then Animaniacs.
Kinda giving away my age, but Animaniacs was right around the time I just started appreciating characters such as Minerva Mink and Hello Nurse.

Transformers, robotech, thunder cats, M.A.S.K, starcom.
- For a shameless toy commercial cartoon, MASK had a pretty slappin intro theme

Underdog, Batfink and Karate, Rocky and Bullwinkle
- Batfink was a favorite of mine too! First time I've seen it mentioned out in the wild.
- I loved Rocky & Bullwinkle! Before my time but we had so many VHSes.

90 minutes of Looney Tunes.

Rugrats Marsupilami Spider-Man Gargoyles
Not tv cartoons, but cartoons either way: Mortadelo y Filemón Astérix

My all time favorite was Robotech, though it has not aged well.
I also went through a lot of Disney in my youth:
Gummi Bears
Duck tales
Darkwing Duck
And then there was the smattering of others:
Dungeons and Dragons
Thundercats
- Robotech
  Blew my little mind away
- Don't forget Chip and Dale's Rescue Rangers

Avatar The Last Airbender. I’m in my early 30s and do a rewatch almost every year.

Thundercats original series, and the original Dungeons & Dragons.

Samurai Pizza Cats. My grandma would have tapes of it so whenever I went over to my grandma's house, chances are this show would be playing at some point haha. The episode I remember the most is the one with the dragon.
- I used to love catching this on a TV channel early in the morning before having to go out to the school bus stop.

South east Asia:
Voltes V
Mazinger Z
Daimos
Macross
Transformers
Thunder cats
Mask
Dino riders

As a kid in the '70s, all the cartoons on Wednesday afternoons kids matinee...Vicky the Viking, Maya the Bee, Heidi, Remi, Pink Panther & Hong Kong Phooey.
- Hong Kong Phooey holds a weird place in my brain. Like, I love it, but not for any good reason.
- Europe I suppose?

Doraemon
This is a very big franchise in Asia but rarely mentioned in the west, so let me introduce it to (most of) you :>
Doraemon is a robot cat from the 22nd century who has gone back in time to help a kid named Nobita. He has a lot of wacky gadgets to offer. Each episode is basically a story about one of these gadgets. They also pump out a new movie every year.
- Doraemon is incredibly popular in Spain, to the point that basically everyone no matter the age knows at least the premise and the main characters. It baffled me when I found out that it was largely unknown in other western countries.
  Edit: I just remembered Shinchan, another anime that is huge in Spain but not very popular elsewhere.

Professor Kitzel.

Mighty Orbots, just for the theme song alone. Now that I think about it I will have that song stuck in my head all day.

I was a fan of Jonny Quest, the banana splits although that wasnt strictly a cartoon nor was Sigmund the sea monster and hr pufnstuf

Once I turned 10: SpongeBob and the Simpsons
Before that: everything, including Pokémon, GummyBears, Darkwing Duck, I am Weasel, recess… I just loved everything!

Imma bend the rules:
Thunderbirds.

So many... The earliest cartoon I remember loving was The New Adventures of Winnie the Pooh. It was incredibly cozy. Then I discovered Cartoon Cartoons, especially Powerpuff Girls, Johnny Bravo, and Dexter's Laboratory with their throwback art styles, and got obsessed with those for a while.
Eventually SpongeBob came out and became my personality, because he was basically an annoying kid trying his best to be friends with everyone like I was. (It's played out now, it wasn't back then.)
ETA how did I not mention classic Looney Tunes. Before we had cable I was really into the classics.

Duckman. I still fall asleep with it sometimes.
- That's not quite a children's cartoon...

Probably Teen Titans

I would say Ginga e Kickoff
https://anilist.co/anime/12875

Starblazers
Robotech
Battle of the Planets
Dinosaucers
Space Pirate Captain Harlock
- Haven’t thought about Harlock for decades, thanks for the reminder! I never saw Dinosaucers but the rest were ace.

SpongeBob
Justice League and Justice League Unlimited

I was never really into cartoons but I enjoyed Pee-wees Playhouse.

Between the Lions. There were far too many Dad puns for my little brain to handle. It broke me

What happened to Tazmanian Devil?
- Do you mean Taz Mania or the original Taz shorts (Looney Tunes/Merrie Melodies)?

Alfred Jodocus Kwak
It's a Dutch show that was beautifully drawn and animated in Japan. It still looks fantastic and it takes you seriously as the material is quite mature. It's about ww2, sort of like deep space 9. There's a lot of world exploration and adventure and it adresses societal issues. The only bummer is that the gender norms are quite old fashioned so it might not be appropriate for your kids based on your views.
