Outside of X-Men, nah. I watched Spidey, but I wasn't much of a fan because he couldn't do anything, The Avengers was dumb, didn't care for the Fantastic Four, and I don't remember Iron Man being particularly good.

I honestly don't remember the Hulk beyond it's intro.

I believe you mean Mighty Morphin Poweravengers:lol

Oh yeah, they all had that stupid armor thing, didn't they? :lol

Everyone except Tigra I think. :lol

They even had long suit up scenes too.

Yeah, I remember that scene. xD

The Avengers were dumb, I'll grant you. Rusty and Big Guy? That show was a treasure among Crap. Spider couldn't do anything? It did bother me that they numbed Carnage. I remember the reason to, the head of Marvel at the time said "Obviously we can't show Carnage killing people on Saturday Morning TV, despite him being a serial killer. But you know he's capable of that, so we don't have to show it". You have no idea he's capable of that if you're first introduction is the cartoon. Iron Man though I loved, but the second season was so much better. The theme song along stepped it up a notch. Incredable Hulk was confusing more than anything. It never seemed to have a real story moving through it, just random Hulk violence. And FF was.. really Kiddish. I never liked that, and the animation style was just weird.

X-Men though should be heralded as one of the great television series' of the 90's. It had the story, the characters, the devolopment, the animation style. There may've been a little to much Jubilee towards the begining, but I loved it all the same. And it had some really great stories. And almost all of them had to do with Apocolypse, Magneto, Wolverine, or Mr. Sinister. I even enjoyed Wolverine and the X-Men, I was saddened with Nick cancelled that.

Although how you can make an Avengers cartoon and NOT have Captain America, Thor, Hulk Or Iron Man be a part of it is beyond me.

They found a way. And they were there, as pictures on the wall. But even then it wasn't really them. It was the New Heroes them from the world created after Onlsaught was destroyed.

Ironically, I'm not an X-Men fan. I actually hate the X-Men. But I know a good cartoon when I see one :p

Spidey it always felt was just hopping around until the villains got tired of firing their non-lethal lasers and the Spider Slayers were deployed so he could actually fight back (Since, god forbid, we show Spidey fighting against a non-robot character. He might hurt them!). Combined with dull animation (It always felt like, outside of fight scenes, the entire freaking series was played in slow motion. And that's not a compliment to the speed of the fights. It honestly felt like they took normal scenes and intentionally slowed them down) and stupid plots (Even for a Spider-Man story), and it was more just "I'm watching this because there was nothing else on."
What they did to Carnage honestly didn't bug me since, well, obviously they weren't gonna put a serial killer on Saturday morning TV. Honestly, him taking a perverse joy in stealing souls (Or whatever they had him doing) was the best they could do, and I understand that.

As for Iron Man, I'll admit that I don't remember much of his show.

The whole series of Iron Man is on Netflix now. And I completely agree about Spider-Man. The stories made little sense, but the worst offender was the finale. That whole multi-verse Spider-Man arc and him meeting Stan Lee at the end. And never finding Mary Jane.
