Please help! In search of special 90s dragon toy!
 

Okay this has been driving me nuts for years

I have been looking for a dragon toy I had as a kid and I cannot for the life of me remember the name of it or the company that made it, but I know exactly what it looked like and it was very unique.

I know it was made in the 90s, around 97-98 I think when I was a kid. It's a black dragon with 3 heads, two on the side being detachable. The belly is silver and it has a little knight in purple armor that rides on its back.

There was also a red dragon that was a part of the line, but again no idea of the name and I can't find a picture reference for that one either.

The only reference I have for this black dragon is an image I found on ebay and even that person has no idea what this toy is called.
If someone could please help me that would be awesome!
