Close-up of the buckle, has gotten fans talking that it looks a bit like items from Goseiger, the 2010 Super Sentai that comes after Shinkenger, the source of Power Rangers Samurai. Could Bandai/Saban be planning to use the Goseiger footage for Samurai much like Dairanger was used for Season 2 of MMPR? To me, it looks like a Samurai head, more like the Samurai Megazord. But anything can happen.
The symbol of the Goseiger, combination of the three tribes: Air, Water and Earth.
Master Head, the Goseigers' boss, which many fans are now referring to as Zordon. For those new people who might not know, Zordon was the first mentor to the Power Rangers and died in the 6th season. But he can always come back. And one of the reasons fans connect these two characters because they are both big blue heads that are mentors.
