Cecil's best friend and dearest rival. He feels deeply, but is ill-practiced in expressing that which he feels. Though he swears to stand by Cecil in his revolt against their unjust king, his heart is consumed by his secret love for Rosa and as a result of this weakness his conflicted mind is easily taken over by Golbez.
—Online description
Cecil's friend and rival since childhood and commander of the dragoons of Baron. He is controlled by the enemy and uses base betrayal to deliver the Crystals to his dark master, but he will atone before the end.
Kain has the highest raw strength tied with Sephiroth, and possesses good agility which can be boosted further. Most of his abilities focus solely on power, so the player can safely prioritize Kain as a pure enemy crusher. As a downside, he lacks a Limit Break and his ability slots are limited.
While Kain gains a number of defensive skills, his high Strength coupled with obtaining a Limit Break that syncs with his power ensures he's a a force to be reckoned with. A major downside is that his Agility has been drastically reduced, and his Spirit is the weakest of all playable characters, making him vulnerable to magic-based enemies.
Kain's Limit, Dragoon's Pride, deals damage to boss-type enemies in direct proportion to Strength, Agility, and Level.
