Few images of some Filming out Saitama Super Arena had been leaked online. In the images Kyoryuger are seen posing but the upper half of their suit is different from their actual suits.
Just like how Hongo Takeshi (Kamen Rider 1) didn't consider Kamen Rider Gaim as True Kamen Rider in Kamen Rider Taisen, even Aka Red still doesn't consider Doubutsu Sentai Zyuohger as a True Super Sentai. So, he starts Super Animal Taisen (not Super Sentai Taisen). By the way, Aka Red's badge got upgraded to 40 V (not 40 Volts).
