I'm sure sixth heroes can sell by themselves. Figures that differ radically sell much easier then figures that are similar to each other. Wolzard Fire would probably be exclusive or something.
they make around 10 or more new kamen rider figures every year, adding DBZ and Pure Cream thing....that's a lot. just adding all 5-8 sentai is not that hard....maybe just the red sentai
Yeah the custom looks pretty decent. But compared to normal figuarts it´s almost a bit S.I.C looking.
But I think it could work. And what lacks the Sentai Senshis in detail they could make up for with more acessories. For example the shinkenmaru and the personal weapon of each shinkenger.
