The twelfth and final episode of Thunder 3 aired recently, concluding a season that has drawn mixed reactions from viewers. Community ratings placed the episode at 3.3 out of five, reflecting a divided response. The episode was released after a one-week delay and includes a six-minute recap before the credits, which some viewers noted as excessive padding.

Critics observed that the pacing has been inconsistent throughout the season, and the climactic moments featured in episode 12 might have been more effective earlier in the run. The episode revisits familiar animation sequences from the previous installment, relying heavily on reused footage rather than introducing new action.

The narrative centers on Futaba, who continues to explore the alien vessel. Her brother Pyontaro, reacting to what appears to be the death of a friend under an alien attack, boards the mothership and moves through the environment without a clear objective. A large mecha with a red-lensed visor, teased in promotional material, appears only briefly at the episode’s end and does not engage in the anticipated battle.

The fate of Pyontaro’s companion remains unconfirmed, and a new antagonist is hinted at without further explanation. These unresolved threads are expected to be addressed in a second season, which has been announced by the production committee.

The episode also coincided with public disclosures by the creator of the original Gantz manga, Hiroya Oku, who revealed himself as the writer behind Thunder 3 under a pseudonym. This revelation was interpreted by some observers as a marketing maneuver timed with the finale’s release.

Despite these elements, the episode contains moments where the mecha design and background artistry stand out. Some viewers have suggested that a more concise edit, reduced focus on peripheral characters, and tighter storytelling could have improved the overall reception. The series is currently available for streaming on Netflix.
