Super Robot Wars/Impact/Unit Acquisition Timeline

Unit and Pilot Acquisition Timetable

Those in Black join your team.

Those in Orange are available for that stage, then leave. Usually denotes temporary characters and units you cannot train/upgrade. Tobikage is a special exception as a guest unit, and upon the beginning of a player phase will combine with Kurojishi, Bakuryu or Houraiou if one has more than 110 will (Whichever has the highest will will be combined with, and if there is a tie it will check again next player phase).

Those in Blue have special requirements.

Those in Red previously joined, but during or at the end of the stage, are rendered unusable. Those lost permanently are marked so, while others rejoin later on.
