I have no idea where this mysterious weapon came from. It seems to be made of a pale, translucent material. Wonder if it's cold to the touch.

We found this unconfirmed weapon while tracking down Cycloid Gamma, who escaped the last time. It seems to be working in order to shut down the rampaging Cycloid Gamma. Anything other than that is a complete mystery. However, it does seem to be learning the techniques of other fighters, similar to Cycloid Gamma.
And now for a comment from one of my great mentors!

Together with Cycloid Gamma, we wanted mysterious characters. At that time in the programming world, techniques like mirror processing, light refracting on transparent bodies, flame expressions, etc. were starting to gain popularity. I remember we definitely wanted to take advantage of them in EX, but we ran out of time, so at least wanted to put a groundbreaking character in the game, and then later we could reintroduce them with a more interesting expression.
