Fate/Grand Order Arcade will get an exclusive character, Larva Tiamat, from December 16, 2021. She will appear as a 5-star Alter Ego Servant. Her banner will run from December 16, 2021 to February 3, 2022. So far, there is no news as to whether or not a playable version of Tiamat will appear in the mobile version of Fate/Grand Order or not.
There is also a short trailer showing off how Tiamat will play in combat. Her attacks are mostly long-range, and her Noble Phantasm briefly transforms her into her dragon body. Aoi Yuki will reprises her role as Tiamat in Fate/Grand Order Arcade. She also voices Okita Soji, Ganesha, and Shuten Douji.

『Fate/Grand Order Arcade』にて12月16日(木)AM10:00より「★5(SSR)ラーヴァ／ティアマト」の実装が決定！これを記念し、期間限定「★5(SSR)ラーヴァ／ティアマトピックアップ召喚」を開催いたします。詳しくは→https://t.co/tEz1UTCtIT #FGO #FGOAC pic.twitter.com/M09O5UcPc1— 【公式】Fate/Grand Order Arcade (@FGOAC_project) December 14, 2021
Though they share the same name and general setting, Fate/Grand Order Arcade has been slowly breaking away from the original Fate/Grand Order. Not only are the events of the Singularities slightly different, but Fate/Grand Order Arcade has characters who are not in the original game. For example, Sita, who is on the same pick-up banner as Larva Tiamat, is only available in the arcade version.
There is one case in which a character debuted in the arcade version before becoming playable in the mobile game. Earlier this year, Jacques De Molay appeared when Fate/Grand Order Arcade launched its Sixth Singularity. During The Halloween Rising Event , a female version of Jacques debuted as a limited SSR Foreigner. However, despite sharing the same name and being based on the same person, they are two completely different characters.
Fate/Grand Order Arcade is readily available in arcades in Japan, and the Larva Tiamat banner will run from December 16, 2021 until February 3, 2022.
