So, OOO will have the silver combo next week. Also known, even in episode previews, as the Gravity Combo. Which, presumably with other materials released about the forms, seems to mean to some extent can control gravity.
So, does this mean that in terms of riders, OOO is supreme? With power to control gravity, it seems no other rider could defeat him. Why? Try to get off the ground to do a rider kick now, any other rider!
Though OOO is too cool and nice of a dude to actually pull such an asshole move.
