Blue Dragon and Zeromus (blue hairy version vs Golbez & FuSoYa)

If by all elements you meant only Fire, Ice and Lightning, the Chimera family would add up (Chimera, Chimera Brain, Chimerageist), and Zeromus (blue hairy version vs the party, also absorbs Holy).

Q. What summons do the party not fight against their lunar counterpart? (GBA)
