I remember watching an Iron Man cartoon on TV. I don't know the name of the original TV series because I watched it in a TV show Fox Kids which used to show different cartoons each day without disclosing its name. The TV show was probably a partnership between TV channels viz. Fox Kids (US) and Star Plus (India). Something more about the cartoon: MODOK and Mandarin were villains. Mandarin had real magical powers of rings unlike Iron Man 3 movie (in which he was a fake terrorist). War Machine was also in it. In the Intro, Tony used to put on the helmet using electromagnetic/invisible force, not like this (but, it can be Intro of different season, not necessarily different TV series).

Now, about the episode I am looking for:

• Pepper was kidnapped or lost.

• Iron Man found her, but he went out of power.

• The scene: It was a vertical tunnel. Underground.

• Pepper had a Walkman with her.

• Iron Man connected a wire coming out of his finger to the Walkman and told Pepper to play it on high volume (LOL!).

• And, it worked.

There can be a little bit variation because the images in my memory aren't 100% clear. Can you please identify the episode? I have already Googled.

Note: This is the first Iron Man thing I ever watched, so there are emotions attached with it. After answering, you can ask for hefty bounties if you wish. :-)
