Have you been watching the Super Hero Squad Show on Cartoon Network?  It's a show meant for the younger viewers but it does have things you can enjoy as well.  What I really like is how there isn't a set group of lead characters.  You never know who will be in the spotlight in the next show.  Actually, I'm going to tell you who.  On Saturday, October 3, 2009 at 8:30 you can catch the third episode (guess we're not counting the pilot as episode 1) on Cartoon Network.  In "Hulk Talk Smack," Hulk gets gray (and smart).
 
After fighting Klaw and Screaming Mimi, the Incredible Hulk becomes the Intelligent Hulk.  As the other heroes are fighting to save Super Hero City, Falcon and Wasp have to babysit the radically changed Hulk.

Never heard of it before. Probably because i'm not American. :p 
 
Are they only Marvel characters or from other companies as well?

It is a U.S. show but it's airing in Canada Teletoon and will stark in the UK this month on NickToons.  Not sure where you're from.
 
It is just Marvel characters but potentially any Marvel characters can show up.

Well I'm from Holland but if it's going to be aired in the UK, it won't be long until it makes it way over here. 
 
Hm.. does sound interesting but it probably won't be succes here, Marvel isn't too popular over here.

at the intro of every episode when hulk gets the fractal he turns into grey hulk really quickly and then they zoom out and show Thor Chasing MODOK

I am actually enjoying this show a great deal. It almost brings me back to when Saturday morning cartoons were good. Most of the characters characterization are spot on to what one would want for a kids show. Stark can't be a drunk womanizer so he's a know it all, I can only imagine how bad Reed will be :) Cap is the stereotypical gung ho military type. And lets not forget Hulk, I was never a huge Hulk fan but whenever he's on the screen I have to laugh cause he's always doing something fun, wither its yelling at the phone to prove he's the loudest there is or just running through walls when a door is right there. I hope this show has a long and healthy run.

This looks fun. They aren't taking it seriously and they're up-front about it, so you have to appreciate it for what it's presented as. I'm kinda looking forward to it...

so its Mini Marvels animated?
Awesome

My daughter thought it was funny that Abomination had stink issues.  Earlier this week I was driving her to school and we drove through one of those random farty smelling areas and she started waving her hand in front of nose and said, "It smells like the Abomination..."  Cracked me up.

GO grey hulk

" @damswedon: I really wished they made a cartoon based on Mini Marvels.  It's a little more mature and funny as hell.  Sure this is a marketing venue for the toyline but I say if it gets the 'kids' hooked and more importantly educated about comics and the characters, great.  Most kids know the main characters but they probably didn't know about characters like Wasp, Falcon or MODOK.  Everyone should know about MODOK. "

that was awesome

Trailer looks good

i saw one episode, not bad, not great.
I noticed a lack of Cap in the show, not only in the episode i saw but in the opening sequence too.
Personally I love cap, and am surprised they aren't trying to use him more.  
After all who's a better role model for kids?

I just saw it today and it was great my son loved it
