I loved to see Daigoyou have a humanoid form, kinda similar to GoRoader GT. So it wll be Seven Samurais.
ugh, I always hated this rumor or fact or w/e it was. Daigoyo, did nothing to even remotely show he was a samurai, so I wouldn't even assume he was either.
Now if their was some one to be called a 7th samurai (IMO) it would be Jii. He's always had the Shinkenger's backs and showed a couple times, he can come through in combat also.
