Crimson Blaze is the first main expansion in Pokémon TCG Pocket’s new B-series, coded B1a and built around Mega Evolutions for the original Kanto starters. It follows Mega Rising (B1) and keeps pushing the app toward bigger, swingier turns with high-damage attacks and stronger evolution support.
Crimson Blaze release timing and structure
Crimson Blaze launches globally on December 17, 2025 as part of Pokémon TCG Pocket’s B1 cycle. The set goes live at 6:00 a.m. UTC, which lines up with a late-evening rollout on December 16 in US time zones. Pokémon’s own announcement highlights a start at 10:00 p.m. PST on December 16, 2025, which is the same moment converted to Pacific time.
Within the app, Crimson Blaze is treated as a full expansion rather than a mini-pack. It is the thirteenth overall expansion and the eighth “themed” expansion that sits alongside earlier A‑series drops such as Genetic Apex, Mythical Island, Space-Time Smackdown, Triumphant Light, Shining Revelry, Celestial Guardians, Extradimensional Crisis, Eevee Grove, Wisdom of Sea and Sky, Secluded Springs, and Deluxe Pack ex.
The expansion is described as the first main B‑series set and is split into three booster packs inside Pocket’s booster menu. The exact number of cards and secret rares has not been announced yet.
What Crimson Blaze is built around
Crimson Blaze revolves around the Kanto starter Mega Evolutions: Mega Charizard Y ex, Mega Venusaur ex, and Mega Blastoise ex. These are positioned as the flagship cards for the expansion and are shown with new immersive card treatments in the official reveal. The expansion also introduces support pieces that clearly push both evolution-heavy and high-pressure playstyles.
Mega Evolutions themselves were introduced into Pocket with the Mega Rising set. Crimson Blaze takes that groundwork and focuses it on the iconic trio of Charizard, Venusaur, and Blastoise, as well as on Trainer cards that fetch Mega Evolution Pokémon ex or accelerate into them.
Crimson Blaze booster pack and in-game event window
Inside Pokémon TCG Pocket, Crimson Blaze appears as its own booster entry, with a dedicated Crimson Blaze pack featuring Mega Charizard Y ex on the wrapper. The associated event period starts at 6:00 a.m. UTC on December 17, 2025 and follows the usual Pocket rhythm where a new expansion shares space with ongoing B1 packs such as Mega Rising.
The expansion also ties into Solo Battles within the app, with new decks expected to showcase Crimson Blaze cards once the set is live.


All revealed Crimson Blaze Pokémon and Trainer cards
The full B1a card list is not public yet, but several Pokémon and Trainer cards are fully revealed, including attacks, HP values, and effects. The table below groups everything that is clearly identified as part of Crimson Blaze so far.
| Card | Type | Role / Effect (summary) |
|---|---|---|
| Mega Charizard Y ex | Fire | 220 HP Fire-type Mega Evolution ex. Crimson Dive deals 250 damage and also damages itself for 50, trading self-harm for very high output. |
| Mega Venusaur ex | Grass | 240 HP Grass-type Mega Evolution ex. Critical Bloom hits for 120 and leaves the opposing Active Pokémon both Poisoned and Asleep. |

| Bulbasaur | Grass | Basic 60 HP Grass attacker with Tackle for 20 damage and a Fire weakness. |
| Charmander | Fire | Basic 60 HP Fire Pokémon. Bite deals 40 damage; weak to Water, with a straightforward single-attack profile. |
| Squirtle | Water | Basic 70 HP Water Pokémon with Tail Whap for 40 damage and a Lightning weakness. |
| Charmeleon | Fire | 80 HP Stage 1 Fire Pokémon. Ignition Ability lets you move a Fire Energy from the Energy Zone to your Active Fire Pokémon when you evolve into it. Steady Firebreathing deals 50 damage. |

| Spritzee | Psychic | Basic 60 HP Psychic type. Sweet Scent heals 20 damage from one of your Pokémon, giving low-cost sustain. |
| Serena | Trainer – Supporter | Searches your deck for a random Mega Evolution Pokémon ex and adds it to your hand, streamlining Mega game plans. |
| Clemont | Trainer – Supporter | Finds two random cards from among Magneton, Heliolisk, and Clemont's Backpack and puts them into your hand, supporting a specific Lightning-style shell. |
| Quick-Grow Extract | Trainer – Item | Targets one of your Grass-type Pokémon in play and evolves it directly with a random Grass Pokémon from your deck that evolves from it. Cannot be used on your first turn or on a Pokémon played this turn. |
Outside the main B1a list, several Promo-B cards (Mega Latios ex, Mareep, and Heliolisk) are shown alongside Crimson Blaze visuals, but they are labeled separately as Promo-B and not part of the core expansion numbering.
How the revealed cards shape gameplay
The early Crimson Blaze cards make it clear that the expansion is pushing three main ideas: big Mega Evolution finishers, more reliable evolution chains, and flexible utility bodies.
The three headline Megas are all multi-Prize threats with large HP pools and high damage ceilings. Mega Charizard Y ex leans on raw numbers with Crimson Dive’s 250 damage, at the cost of hitting itself. Mega Venusaur ex layers status by forcing both Poison and Sleep on the opponent’s Active Pokémon, which can effectively lock down a board if the opponent cannot switch or cure conditions quickly. Mega Blastoise ex spreads damage, threatening two Benched targets for 50 each when you invest extra Water Energy.
Charmeleon and Sunflora show how Crimson Blaze rewards players for building around evolution lines. Ignition turns Charmeleon into a one-time Fire Energy acceleration tool when it enters play as an evolution, which supports both Mega Charizard Y ex and other Fire ex attackers in Pocket’s card pool. Sunflora ties directly to Quick-Grow Extract, gaining extra damage when that Item is in the discard pile and turning what would be a simple evolution Item into a damage enabler.
Ditto stands out as a flexible Colorless tech card. Copy a Friend allows Ditto to borrow attacks from non-ex Pokémon on your Bench as long as the Energy costs are met. That turns it into a kind of universal backup attacker that can pick whichever attack the board state demands, though it deliberately avoids copying the most powerful ex attacks.
On the Trainer side, Serena compresses Mega Evolution setup into a single Supporter use by pulling a random Mega Evolution Pokémon ex directly from your deck. Clemont points to dedicated Lightning lists with Magneton and Heliolisk, and Quick-Grow Extract lets Grass decks jump an evolution step without waiting a turn, as long as the usual “no first turn” and “not newly played” constraints are respected.
Cosmetics and accessories tied to Crimson Blaze
Crimson Blaze is not just about cards. The expansion arrives with new collection cosmetics, including covers and backdrops featuring Mega Charizard Y. These cosmetics let you theme your binder-style collection and display boards around the new flagship Mega.
Pokémon outlines a separate rollout for these visuals, with Mega Charizard Y covers and backdrops available starting on December 31, 2025 at 10:00 p.m. PST. They sit alongside existing Pocket cosmetics such as coins, sleeves, playmats, icons, and emblems.
Crimson Blaze is positioned as a pivot point for Pokémon TCG Pocket’s B‑series: it anchors the Mega Evolution mechanic to one of the franchise’s most recognizable trios while quietly reinforcing core evolution and search patterns. As more cards are revealed and the full set number becomes clear, expect Fire, Grass, and Water lists built around these Megas to define a large share of the early B1a metagame.
