Then Shun will probably become the new Fourze.
What if Gokaiger chose the Greatest Treasure at the end?
Then they'll probably be their most powerful. For example, all the pirates might
have same Tyrannoranger suits, powers, weapons, coins and henshin devices
when one of them makes identical Zyuranger Ranger Keys of that ranger and
the gang use them, they will be able to combine other sentai zords and ships
with the ones that the Gokaigers already gained to create new zord
transformations, gain the memories of past Super Sentai teams, etc.
What if there was a two-parter that had The Gokaigers entered an
alternate universe, come to blows with their anti-villain counterparts,
get owned by them and findng out a way to stop their counterparts
before they figure out how to crossover into their world and conquer it?
