Dantetsu-san and Shinya-san have quite different fighting styles. Dantetsu uses mainly fists, while Shinya is training to emulate his ancestor's martial art style. Other than that, Shinya's suit is much duller than Dantetsu-san's.

I'm sure there would be an orange, had Deinosgrander stayed a Zyudenryu instead of becoming a Guardian. If they all had survived, there'd be 24 of us...especially if someone had been chosen to be Tobaspino's partner.
