Oh fuck! My best friend had those exact bionicles when I was a kid!
I was a Beast Wars fan, although I was too young when I watched it to remember much of the plot other than Megatron saying "Yeeees" a lot, and thinking Tigon was cool.
I had this Beast Wars Transmetal toy when I was a single digits old.
I wish I still had it, but unfortunately he was one of my favourite toys and eventually after many years his legs fell off and he was thrown out by my parents.
