Yeah, I agree with PrimoPiccolo. And I am pretty sure that Dogabaki form won't let us down. And I can also guess that by trusting all of his 3 arm monsters, Wataru comes closer to them and is able to understand more about the past. Also, I would like to see this form against Rook.
I am rather confused though with the fact the the rumours about Bishop appearing were not true in the end.
Last year, I watched both Gekiranger and Den-O, and I must admit that Gekiranger was way better. This year, after both Go-onger and Kiva air, when I go to the web to read the synopsis of the new episodes, I first go to Kiva, since this year it has proven that it is the best of the two. Not that Go-onger is bad, but Kiva's drama and horror style mignled together with the amazing storyline and generally the whole idea of connection between 1986 and 2008 (which remains a mystery to most of us) puts it in front of all of this year's series. If I had to compare Gekiranger with Kiva though, I would say they are equal, each in its own perspective.
