Looking for non-transformers toys!

I'm looking to the community to help me on this. Although Transformers are my #1 favorite toy ever, I am looking to find other types of transforming toys that aren't released within the US.
For instance, does anyone remember Big Bad Bettle Borgs? Or Power Rangers?
I am looking for any and every type of toy that can transform from a vehicle/animal/ object of some sort, into a robot.
If anyone can provide a list of various brands, toys, shows, whatever, that has anything in relation to this, I would be forever grateful.
I know of many third party toys for transformers, so please avoid those.
Knock offs are welcome too, as I am looking for OVERSIZED Transformers toys as well.
