What's noticeable is that each Rider has their own version of the Sonic Arrow, the default weapon of the Riders that used the Genesis Driver in the show. In the series, the said weapon only has one default look, but in S.I.C. form, each Sonic Arrow is based on how each Rider looks like.
Sadly, details and price of each figure weren't revealed in the event.
