Cid (The After Years boss)

Cid is fought as a boss in a flashback in Final Fantasy IV: The After Years at the end of the Lunarian's Tale.

Strategy
The encounter is a recreation of Golbez's defeat at the hands of Tellah's Meteor. Cid is merely an observer to the battle, and though he can be targeted for spells and attacks, neither he nor any of the other party members can be felled before Tellah casts Meteor, ending the fight in a cutscene.
