I had considered that (Infact it's really ironic, since the appearance of 14&15's arrival in the city is just like how Trunks told them about the Androids) However, that scenario doesn't work.*PINHEAD* wrote:Maybe Androids 13-15 were the androids they fought. 17 and 18 could have been destroyed by 13-15. So instead of the Z Senshi defeating 17 and 18, and then 13-15, it could have just been 13-15. And then Trunks, future, Cell, DB timeline, Room of Spirit and Time, Cell go boom.
We can assume that the intro scene from the movie follows the series story up to that point. 19 is missing, Dr. Gero is missing his hat and arm, and 17 kills Gero in the same fashion, and 17 smirks up at the open doorway (at the unseen Z senshi).
Fast forward to the movie, now everybody is relaxing in the city, not searching for 17 and 18 or 20. This heavily implies that the androids at this point are dead. (Poor Kuririn)
