This past weekend on Fuji TV in Japan, a special showing of the Dragon Ball Z: Resurrection “F” movie took place – Future Trunks Special Edition. It included 30 minutes of footage that wasn’t in the theatrical or Blu-Ray/DVD release.
One of the items shown was Goku going Super Saiyan for the first time. In the video below, the remastered version of this event is shown from the Dragon Ball Z: Resurrection “F” – Future Trunks Special Edition along with the original one from Dragon Ball Z for comparison.
The footage of Future Trunks and Goku Black, much of which looks familiar from Dragon Ball Super, can be seen below starting at the 1:15 mark.
