Union Arena Attack on Titan UA23BT Card List: Chases, Parallels & Signatures
Looking for the Union Arena Attack on Titan UA23BT card list? This collector guide focuses on the cards most worth knowing about: Super Rares, high-rarity parallels, foil-stamped signature cards and the serial-numbered AP chase, plus the exact Japanese booster-box format.
The Japanese set contains 35 Common, 35 Uncommon, 18 Rare, 12 Super Rare and 6 Action Point card types. Bandai also confirms parallel cards, newly drawn artwork, foil-stamped signature cards for five Japanese voice actors and a very low-rate serial-numbered AP campaign.



What are the main UA23BT chase cards?
The clearest collector targets are the high-rarity character parallels for Eren, Mikasa, Levi, Armin and Erwin, because Bandai specifically built the product around foil-stamped voice-actor signature cards. The set also has a separate serial-numbered AP card campaign, inserted at a very low rate and in limited quantities.
| Card | Rarity / treatment | Why collectors notice it |
|---|---|---|
| UA23BT/AOT-1-092 Eren Yeager | SR / SR★★ parallel | Major protagonist with a premium parallel treatment. |
| UA23BT/AOT-1-089 Mikasa Ackerman | SR / SR★★ parallel | Signature-style premium parallel shown above. |
| UA23BT/AOT-1-010 Levi | SR / SR★★ parallel | One of the headline signature characters. |
| UA23BT/AOT-1-002 Erwin Smith | SR / parallel versions | Another character included in Bandai's signed-card lineup. |
| Serial-numbered AP | Limited AP chase | Bandai describes these as very low-rate, limited-quantity inserts. |
More UA23BT collector hits: 1-star parallels
The chase list should not stop at the SR★★ cards. UA23BT also has one-star parallels on lower base rarities, which are still proper parallel hits and are useful for character collectors. Two good examples are Hange and Sasha:


Other notable standard hits worth recognising include Armin Arlert SR, Erwin Smith SR, Reiner Braun (Armored Titan) SR and Bertholdt Hoover (Colossal Titan) SR. These sit below the headline signature-style parallels but are still meaningful pulls from an Attack on Titan box.
UA23BT premium parallel gallery
The hit pool goes well beyond the first three cards shown above. Bandai's card database also includes additional premium character parallels, including Eren at the three-star tier and more two-star / parallel treatments across the cast.




More UA23BT parallel hits



These sit alongside the existing Mikasa, Levi, Hange and Sasha parallel examples, so the box has a much broader collector hit pool than just the headline Eren card.
Notable Attack on Titan UA23BT cards
Beyond the signature chase cards, the official card database identifies multiple key Eren variants. UA23BT/AOT-1-094 is an SR Eren Yeager (Attack Titan) card, while UA23BT/AOT-1-092 is an SR Eren focused on the 104th Training Corps / Levi Squad strategy. Mikasa's AOT-1-089 SR and Levi's AOT-1-010 SR are also major named cards in the set.
