Nyagoking (ニャゴキング) is a giant robot that aids the Nyanki whenever they get into a tight spot. They are summoned by a signal sent out by Yattaro’s sword. It has two forms; Sphinx mode which is the form it assumes when not being used, and giant robot form for battle. Nyagoking is also what launches Toritsukkun who transform the Cats into the Mega-Up Nyanki. The robot is armed with fish-themed weapons such as a fish spear and fish blaster (both of which are packaged with this figure). When not being used, Nyagoking is stored in a statue in Neko Fujiyama (Edoropolis’ highest mountain).
This figure was the first modern die-cast release of that design — pre-dating the ES Gokin and Heat Boys reinterpretations.
⚙ About the “Dynamite Action!” line
Evolution Toy’s Dynamite Action! series pays homage to the golden age of chogokin mecha toys. Instead of relying on traditional plastic pegs or ball joints, each figure uses embedded magnetic connectors that let collectors swap and reconfigure limbs while maintaining a sleek, vintage feel.
The concept draws inspiration from Go Nagai–era combining robots and 1970s–1980s die-cast designs by Popy and Bandai. The use of real metal (zinc alloy) not only adds a nostalgic heft but also echoes the tactile durability of early robot toys.
In Nyagoking’s case, the line’s engineering allows for seamless articulation, magnetized part swapping, and a sturdy display presence without visible mechanical seams — a perfect balance between retro craftsmanship and modern precision.
