I should think about this more. But right off the top of my head:

Faiz Phone - A very basic futuristic concept that is self sufficient. Backed by one of the smoothest voices in all of toku. The henshin belt is one of the most icon aspects of a rider, and here it is also a weapon!

GX-05 Cerberus - It reminds me of all the awesome Metal Heroes weapons. Transforming weapons are the epitome of cool, but impractical.

Kaixa Blaygun - Dual purpose high tech weaponry. It is used so well in the show with such a great finisher. I could probably fill an entire list of just 555 weapons.


Honorable mention: Revolcane - It's a beam sword/light saber/energy blade. At a very core level, that's a simply cool concept. A kid could have never seen any sci-fi show and yet know exactly what to do with it.
