A very brief overview of henshin devices.
And here’s a link to the news about Toei streaming tokusatsu!

If I had a device that was based on my everyday self (e.g. you having a pen) it would be either a multi-tool (probably a Gerber because they have a better slidey-sound action than a Leatherman) or a phone headset (yay desk job?). If my henshin was just a cool thing for a show that you could sell, how about a special bubble tea dispenser? Different types of “bubbles” could give you different power-ups and each character would have their own flavor of tea =)

My henshin device would probably have to be a Sharpie pen since I have to carry one around at work all the time. Problem is the transformation would probably be a silly Sailor Moon style magic disguise. If it didn’t affect my morning routine I could always put on my glasses and get a hardsuit like on Bubblegum Crisis. That would be cool.
