Grease is mostly because of gold plastic syndrome I believe.

Which is I think gold plastic is a lot more fragile and breaks a lot easily. So any Toku toy that's like gold in a way would probably be just like that.

While not exactly breaking, I do know people had trouble with the FullFull Bottle in terms of it activating at the slightest touch or something like that.

Gold Plastic Syndrome isn't a thing in every gold plastic though, just specific types. Could be that Grease got unlucky.

GPS being a thing with all or most Gold Plastic is a misconception! It effects a very specific type of plastic that was mostly just seen in the late 80s to mid-90s, with a small handful of exceptions running past that in the 00s. 'Gold Plastic Syndrome' is itself a bit of a misnomer, as the common running thread is instead in swirly/metallic/sparkly plastic which has for instance been seen in grey plastic -- it's just that it's most common in gold.

Simply put I would be very very surprised if RKF Grease was down to GPS, and it's certainly not a worry for any other Toku toy that uses gold.

You learn something new every day.

the GP and SG versions of toku collectible items have notably weaker engineering points than their DX counterparts.

Non-DX Shift Cars for example have clips inside them that break pretty easily, but have little effect on the actual operation. If you shake one and hear a rattle, it probably broke.

A lot of the older SICs are super fragile. I?ve heard that Leangle is basically guaranteed to come out of the box already broken.

Which of the girls do you think is the next female rider alongside Na-Go? Tsumuri or Sara?

I for one hope its Sara. For if she becomes a rider herself alongside her brother, what'll be her motif?

Like the others, I for one see her entry in a skirt!

• Geats: Scarf
• Tycoon: Garter
• Na-Go: Bracelets
• Buffa: Coat
• Punk Jack: Cape

I already recommended that Sara could share a motif with an animal-themed Donbrothers character.

I kinda hope it's Tsumuri as her actress is a karate black belt and want for that to be utilized. For the motif, there are still wide variety remaining, from the 30 Riders that participated that mostly got eliminated before the main 7 cast.

It has already been announced that Kamen Rider Reta is a new female character:

Of course, with a high probability she can quickly drop out, but still she is considered a female rider.
