I don’t remember many details other than the fact that I believe it was a green colored rock or blob which gives the holder super fighting abilities, I briefly remember that the kid usually had it in his backpack.

Sounds similar to “The Guyver.” But it was an American film, just BASED on the Japanese manga. Doubt that’s what you’re looking for, but I thought I’d comment, just the same.
“The Magic Crystal”(1986)?
Here is the full movie.https://youtu.be/gyEtD1xuYFM
