I'm probably wrong, but IIRC it had to be that big because if it was smaller it would be unable to support itself. That said, I want to see Lion Ha-Oh and this together.

The more I look at this thing the more I think it's just the BoJ version with remolded parts to work with the BoA toys. The biggest differences I can spot molding wise are the arms, everything else is pretty minor like the lack of gold parts in the back legs, which could just be a change in plastic color and not new parts. Doesn't the Ninja Steel Megazord already fit in Lion Ha-Oh pretty well?

I'm not sure, but I know that the OtomoNin fit the Megazord pretty well (except for the shuriken).

What American parent is going to spend $100.00 to buy a Zord Builder toy for their kid? That is crazy as hell.

Lion Fortress Zord looks bigger than Pyramidas from Power Rangers Zeo..

Yes, they are compatible:

The same parents who would buy their kids Legacy PR figures.
