If Machiko Soga were still alive, they would have brought her back to reprise a villain role in the movie. Soga most notably played Denziman's Queen Hedrian and Zyuranger's Witch Bandora.
A massive battle happened prior to what we saw in the Legend War and it featured over 100 robots fighting the Zangyack fleet. Many of the robots were destroyed or killed during the battle.
