Here are some possible reasons for the confusion:
* You might be thinking of a different episode: There were several Sonic the Hedgehog shows on Fox Kids, and Shadow might have appeared in an episode with a similar title.
* You might be thinking of a different show: There might be a show you're thinking of that features a character that resembles Shadow but isn't actually Shadow.
* You might be thinking of a fan-made story or video: Many fans create their own stories and videos, and it's possible that a fan-made story includes a scene where Shadow dies.
To help clear up the confusion, it would be helpful to know:
* What show were you thinking of?
* What year did you see this episode?
* What do you remember about the episode?
With more information, I might be able to identify what you're thinking of.
