Hm... Eiji switched straight to the full green form, without going part by part; music attempting to sound epic; yelling sequence that lasted several seconds and its own new theme. Also, the only drawback of the green form was Eiji getting tired, but he was perfectly fine one scene later.
Yeah, it's pretty clear that Toei wants people to love the one color forms above anything else. I really don't understand how they had this idea that just hurts their own toys, but now it's done.
