This Goukaiger Promo's HUGE!
I took this picture from Henshin Grid. Anyway looking at it, we do have a LOT of red rangers in this photo and I mean, most of them right now are having a new direction in life. So I really thought of it that aside from Gaoranger being the 25th entry in 2001 (and Timeranger showcased the previous Sentai series in a special episode) and then we have Boukenger by 2006 as the 30th entry, Goukaiger is the 35th season. From what I heard, they will be traveling into different eras so has Sentai's timeline been changed? I don't know. As of recent, Toei said that each show is a standalone though.
