# Mega Greninja ex (Japanese) #098 — M4: Ninja Spinner

## Summary

Mega Greninja ex fills its Japanese full-art frame with a dark, blue-and-red figure in mid-leap, shuriken-like fins fanned out against a smoky crimson backdrop, so the Water-type reads as pure ninja motion. It landed in M4: Ninja Spinner in March 2026 as a chase-slot Super Rare, and that placement drives demand for the Japanese edition. Greninja's pull with fans runs back to its Kalos starter days. The modelled guide sits at $8.11, down 17% over 30 days on 49 copies traded, with 106 days of inventory on the board; PSA has slabbed 1,938 of these and 1,824 are 10s, a 94% gem rate, but no graded market has formed to price the slab.
