[Battlizer]

If a bunch of Riders gathered to stop it, they probably would. Somehow. if there's anything I learned form Taisen movies, it's that the more Riders gathered together, the greater the chances something illogical will happen to give them the victory.

And if they decided to bring Sentai in too...I'd begin to feel bad for Helheim. The overly complex string of contrived false betrayals and unexplained plans would probably annihilate Helheim on the spot.
