The Pokémon TCG rumor mill is buzzing with whispers of Shadow Storm, a highly anticipated mainline set speculated for Q1 2026 in Japan (English release likely Q2/Q3 2026), potentially ushering in a dark, stormy era following the Mega Evolution series! First leaked in TCGTracker’s viral September 29 X post (86K views, 740 likes), Shadow Storm tops a list of upcoming expansions including Emerald Surge, Legendary Dreams, Radiant Ruby/Shining Sapphire, and Eternals (30th anniversary). Japanese sources like BLACKey (297K views) and PokeBeach forums tie it to Dark Tera Charizard ex (inspired by Horizons’ Friede promo DARKTERA0006) and Mega synergies, positioning it as a shadow-themed powerhouse with comic-style Mega Attack Rares (MA). While unconfirmed, the leaks align with trademarks filed in June 2025 and patterns from dual sets like Black Bolt/White Flare.

Leak Origins: How Shadow Storm Went Viral
The Shadow Storm rumor exploded with TCGTracker’s September 29 post, listing it as the next major set after Phantasmal Flames, sparking 86K views and 740 likes on X. The leak, sourced from anonymous Japanese insiders, detailed a “dark storm” theme with Tera Type Charizard ex and Mega Darkrai ex, aligning with Horizons anime’s DARKTERA0006 promo. BLACKey, a reliable Japanese leaker with 297K followers, confirmed “シャドー ストーム” trademarks on October 1, hinting at a Q1 2026 Japan release. PokeBeach forums, with threads garnering 1K+ replies, speculate it’s M4a (fourth 2026 set), dual with “Storm Shadow” for Dark/Fairy focus. Reddit’s r/PokeLeaks (400 upvotes on the original post) debates it as a “Darkrai-led” set with Shadow Lugia VSTAR reprints from Crown Zenith. The timing fits Pokémon’s pattern: trademarks 5-6 months pre-release, like Black Bolt/White Flare’s June filings for July launch. Community sentiment is electric—X users like PokeHEX (36K views) call it “the dark 151 we need,” with speculation tying to Legends: Z-A’s shadow mechanics.
Speculated Cards: Dark Tera Charizard ex Leads the Shadows
Shadow Storm’s rumored roster leans into dark, stormy themes with Mega and Tera synergies:
- Dark Tera Charizard ex: Horizons-inspired (DARKTERA0006), Fire/Dark ex with shadowy flames and “Dark Flare” attack (200 damage + burn, discard Energy for Paralyze). Speculated SIR with eclipse backdrop, HP 320.
- Mega Darkrai ex: Ghost/Dark Mega ex with Nightmare Aura ability (opponent discards 1 card per turn). MA rarity with “BAM!” overlay, HP 310, Dark Void (150 + sleep).
