Just says you are being approached by a toy company and they asked you to pitch them collectible devices for their next Kamen Rider shows.

Not only they want kids to collect those collectible devices but they want the collectible devices to tied in with Kamen Rider shows.

They are like “Alright, pitch us collectible devices for the next Kamen Rider show and make it like something childrens want to get their hand on and it must tied in with the storyline of next Kamen Rider.... so pitch us away!”

Sure, it’s unlikely you will ever being approached by them but this is just a HYPOTHETICAL question.

My ideal henshin trinket has already been made.

Lights, sounds, fidget-quality, and can display well.

OOO's Core Medals were my ideal collectable. I just love 'em so much!

So I would have no shame in recycling that for another show

I love the collectables with some kind of motion feature, so let's take that one step further and give them a wind-up mechanism that you wind up before transforming and then unwinds when used in the driver! Maybe they'd work like tiny zoetropes and play a simple animation when they unwind.
