A Tera Pokemon ex card is a Pokemon ex that has been “Terastallized” — and the one thing every version of it shares is a printed rule, not an in-game ability you activate: while it’s on your Bench, it takes no damage from any attack, including attacks from your own other Pokemon. That single line of rule text, based on the Terastal phenomenon from the Scarlet & Violet video games, is what defines the whole card family.
The mechanic first appeared in Japan on 20 January 2023, and it has since branched into a type-shifted version and a separate Stellar-type version, alongside at least one dedicated high-class Japanese set built entirely around it. This guide sorts out where the mechanic started, how the variants differ, and which Japanese Tera-era boxes we currently list.
A Tera Pokemon ex card is permanently immune to damage while on the Bench — a printed rule effect, not an ability you trigger. The mechanic launched in Japan on 20 January 2023 with the same-day dual release of Scarlet ex (SV1S) and Violet ex (SV1V), the two sets that also introduced the current Japanese UR-based rarity system. The SV1V-Violet ex Japanese Pokemon Booster Box is currently listed at ¥9,880 (~$62), and the dedicated Tera-themed high-class set, the SV8a-Terastal Festival ex Japanese Pokemon Booster Box, is currently listed at ¥17,510 (~$110) — a later set built around the mechanic, not the one that introduced it.

What Is a Tera Pokemon ex Card?
A Tera Pokemon ex card — called a Terastal ex-related card in Japanese naming — is a Pokemon ex card that carries a stylized name graphic and a printed callout beneath the HP line describing its effect: it takes no damage from any attack while it is on the Bench, including attacks from the player’s own other Pokemon. This is permanent rule text printed on the card itself, not a once-per-turn ability you choose to use — it applies automatically for as long as the card sits on the Bench.
The mechanic is built on the Terastal phenomenon from the Scarlet & Violet video games, where a Pokemon takes on a crystalline form and a specific “Tera Type.” On the trading card, that concept translates into the rainbow-tinted crystal styling around the card name and the Bench-damage-immunity rule described above.
Don’t confuse the Bench-damage immunity with an Ability that gets shut off by Ability-blocking effects. It’s printed as passive rule text tied to the card being Terastallized, and it’s active the entire time the card is benched.
Where Tera Pokemon ex Started: Scarlet ex & Violet ex (January 2023)
Tera Pokemon ex debuted in Japan in the Scarlet ex (SV1S) and Violet ex (SV1V) expansions, released together on 20 January 2023. This was a same-day dual launch — two separate booster sets released simultaneously — and it’s the same launch that introduced the Japanese UR-based rarity system still in use across the current Scarlet & Violet era. Our full checklist for one half of that launch, the Violet ex (SV1V) card list, covers all 108 cards in that set.
These two sets are the origin point for the entire Tera Pokemon ex family. Every later Tera-themed set — including the dedicated high-class pack covered below — builds on the mechanic these two boxes introduced, rather than reinventing it.
Type-Shifted Tera Pokemon ex: When the Tera Type Doesn’t Match
Not every Tera Pokemon ex keeps the Pokemon’s normal type. A type-shifted Tera Pokemon ex prints a Pokemon with a Tera crystal effect from a different type than usual — for example, a Grass-type Pokemon carrying a Fire-type Tera crystal treatment. This variant traces back to the Obsidian Flames era of the English-language print schedule. The exact Japanese set that first carried a type-shifted Tera Pokemon ex hasn’t been independently re-verified for this guide, so we’re citing the era rather than pinning it to a specific Japanese set code.
The underlying rule text — no damage while on the Bench — doesn’t change between a standard Tera Pokemon ex and a type-shifted one. The only difference is which type the Tera crystal styling represents on the card face, which changes what the card’s attacks and Weakness interactions look like relative to the Pokemon’s usual typing.
Terastal Festival (SV8a): A Dedicated Tera Set, Not the Original
Terastal Festival (SV8a) is a Japanese high-class pack built specifically around the Tera Pokemon ex mechanic, with additional Tera-themed chase cards layered on top of the base rule text. It’s worth being precise here: Terastal Festival did not introduce Tera Pokemon ex — that happened with Scarlet ex and Violet ex back in January 2023, as covered above. Terastal Festival is a dedicated, later set that leans further into the mechanic rather than the set that created it.
The SV8a-Terastal Festival ex Japanese Pokemon Booster Box is currently listed at ¥17,510 (~$110). For readers comparing it against another high-class Japanese release built around a different mechanic, our Terastal Festival vs VSTAR Universe box guide lines the two up directly.
Stellar Tera Pokemon ex: A Later, Separate Variant
A separate, later mechanic — Stellar-type Tera Pokemon ex — was introduced in an expansion Bulbapedia names “Stellar Miracle.” This is distinct from the original Tera types and from the type-shifted variant described above; a Stellar-type Tera Pokemon ex uses its own crystal styling rather than matching or shifting the Pokemon’s normal type. We haven’t independently re-verified an exact Japanese release date for this variant, so treat it as a later addition to the Tera family rather than a dated milestone in this guide.
Between the three variants — standard, type-shifted, and Stellar — the one constant is the printed Bench-damage-immunity rule described at the top of this guide. The variants change the crystal typing shown on the card, not the underlying rule text itself.
Tera Pokemon ex on the Japanese Rarity Ladder
Tera Pokemon ex cards run through the same Japanese rarity system that launched alongside them in January 2023 — a base Double Rare (RR) print for most Tera Pokemon ex, moving up through Art Rare (AR), Super Rare (SR), Special Art Rare (SAR) and Ultra Rare (UR) for the higher-tier full-art chase versions of the same card. That’s the same letter system used across the rest of the current Scarlet & Violet era, not something unique to Tera prints. Our Japanese Pokemon rarity symbols guide breaks down what each letter means and how it compares to the earlier Sword & Shield naming.
Knowing where a given Tera Pokemon ex sits on that ladder tells you the print tier and foil treatment — it doesn’t tell you the card’s condition or how the mechanic itself works, which stays identical across every rarity tier of the same card.

Frequently Asked Questions
What does a Tera Pokemon ex card do?
A Tera Pokemon ex takes no damage from any attack while it’s on the Bench, including attacks from your own other Pokemon. This is printed rule text tied to the card being “Terastallized,” based on the Terastal phenomenon from the Scarlet & Violet video games — it’s a permanent passive effect, not an ability you activate.
When did Tera Pokemon ex cards first come out in Japan?
Tera Pokemon ex debuted in Japan on 20 January 2023 with the same-day dual release of Scarlet ex (SV1S) and Violet ex (SV1V). That launch also introduced the Japanese UR-based rarity system still used across the current Scarlet & Violet era.
Did Terastal Festival (SV8a) introduce the Tera Pokemon ex mechanic?
No. Terastal Festival (SV8a) is a dedicated Japanese high-class pack built around Tera Pokemon ex with additional Tera-themed chase cards, but the mechanic itself started earlier, with Scarlet ex and Violet ex in January 2023.
What is a type-shifted Tera Pokemon ex?
It’s a Tera Pokemon ex where the Tera crystal effect shown on the card is a different type than the Pokemon’s normal type — for example, a Grass-type Pokemon printed with a Fire-type Tera crystal treatment. This variant traces back to the Obsidian Flames era of the English-language print schedule.
Is Stellar-type Tera Pokemon ex the same as the original Tera mechanic?
No. Stellar-type Tera Pokemon ex is a separate, later variant introduced in an expansion Bulbapedia names “Stellar Miracle.” It’s distinct from both the original Tera types and the type-shifted variant, though the underlying Bench-damage-immunity rule stays the same across all versions.
