Finally in September, a new weapon called "Whale Change Gun", which will transform a Zyuohger into Zyuoh Whale. It is still unknown who will use it, but it seems possible that all of them can transform into Zyuoh Whale. This item has five modes: transformation, final attack, summon, cube transformation, and final gattai.
Zyuoh Whale will get his own mecha, the Cube Whale, which is said to be a giant helicarrier and the final mecha. It is said that we will see more of it in the fourth toy catalog.
