Uses for Gadoras:
1- Used to convert Sealed Dorania in Dragon Princess Anya
2- You can feed it to itself for SU/CR
3- You can feed him to a unit with increase AT III for the SU
4- Since its skill changes after CC, you can CC and then feed him to another unit with increase AT IV
5- When CC'd it is used as AW fodder for Dragon Princes Anya along with a Samurai and a HA
I hope this helped
