# Xerneas GX #90/131 — Forbidden Light

## Summary

Xerneas GX is the Kalos box mascot whose Fairy typing gave it a loyal Gen VI following. In Forbidden Light it was an Ultra Rare, a real chase slot for its set, and 5ban Graphics is a recognizable name among Sun & Moon era GX collectors. The modelled guide sits at $13, up 3% over 30 days on 38 copies traded, with 320 days of inventory on the board; PSA 10s at $189 are only 15 times raw with a 60% gem rate, so grading barely breaks even, and the slabbed population has not grown in 30 days, slower than 87% of tracked cards.
