What kind of time-travel story is this?
Time travel is an important premise, with limited sustained exploration.
Meets the archive’s time-travel criteria. The mechanism is classified as Mechanical.
Why the archive makes this assessment (spoilers)
Confirmed 5/10: Superman sends a grieving Supergirl to the 31st century to train at the Legion Academy. Once there, the story is training, rivalry with Brainiac 5 and the Dark Circle's attempt to steal the Miracle Machine.
Supergirl attends the Legion Academy in the thirty-first century; the dialogue identifies a Time Bubble as the transport device.
Titan combines the archive’s quality, audience and legacy base with the significance of time travel. It is an index, not a score out of 100, and is distinct from the FMV archive’s scoring model.
Partial inputs flag incomplete source metadata. Provisional weighting flags a time-travel assessment that remains uncertain; it receives no additional confidence penalty.
