All Information below is written as if the
movies went along with the dbz series even though they don't it's
pretty much just for fun so read up:
Movie 1 never occurred because Gohan was abducted by Raditz as soon
as he met the Z crew. Movie 1 took place where Gohan was abducted
by Garlic Jr. when he already knew Piccolo and Krillin. If Movie
1 is false, then Garlic Jr. doesn't exist. However, he made an appearance
in the Frieza Series.
2 couldn't have taken place because Kakkarot used the Kaioken technique.
Goku fought Nappa and Vegeta as soon as he learned the technique.
After the battle, he was severely injured so he couldn't have fought
3 Should take place after the fight against Vegeta because Gohan
had the mushroom haircut, but before the defeat of Frieza because
Kakkarot, Trunks wasn't present. If this is so, Tenshin-Han, Piccolo,
Yamaha, and Chauzu should be dead. They fought in Movie 3.
4 False for the same reasons as Movie 3; Piccolo should have been
dead. He appeared in Movie 4. In the remake of the first Dragon
ball episode, Kakkarot starts out wearing a blue suit.
5 Vegeta and Trunks were missing. Kooler boasted that he was here
to kill all remaining Saiyans, but fails to consider Vegeta and
Trunks in his quest.
6 Trunks was no where to be found.
7 Trunks's sword shattered when he used it to attack the fused Androids
13, 14, and 15. In the series, Trunks always had his sword.
8 Our heroes should have been preoccupied dealing with Cell.
9. Trunks returned to the future as soon as Cell was killed. Therefore,
this movie could only be real if it took place between the time
Cell died and the brief interval before he returned to his time.
10/11 False if Movie 8 is. If Brolli never existed, that automatically
makes Brolli's sequel movies fake.
12 False of numerous reasons. Buu was causing destruction throughout
the Earth when the movie took place, but no signs of Buu were seen.
13 Created to try to explain where Future Trunks acquired his sword.
It shows that Tapion gave it to him as a gift.
