Nobody's making a straight toy commercial anymore, so when one actually commits to the bit, you notice. Bakujuu Gasshin Ziguru Hazeru doesn't pretend the mecha swaps are incidental to the plot, they ARE the plot, the way kids actually play with these things. Six episodes of pure mechanical problem-solving: swap a part, the whole tactical situation changes, move forward. It's the toy line animated exactly as it functions in your hands, which means every combination you could build actually matters on screen. If you've ever snapped pieces together and imagined what would happen next, this show is that thought made real.

Bakujuu Gasshin Ziguru Hazeru is a six-episode action mecha short from 2013, built on MegaHouse's Ziguru Hazeru toy line. The robots take their inspiration from figures in the classic tale Journey to the West, and their parts can be pulled from the joints and swapped for others. Three of them, Hazeru Gokuu, Hazeru Sagojo and Hazeru Hakkai, can join together to form a single larger machine called Hazeru Seioh.
