Kain's physical stats are heavily weighted. In 2D releases Kain has no MP growth, and in all releases learns no magic naturally.
Kain's special ability is Jump, which allows him to deal extra damage via an aerial attack. While Kain is airborne, he cannot be targeted and thus avoids attacks. In the Advance and Complete Collection releases, completing Kain's Lunar Trial and defeating Lunar Bahamut rewards him with the Dragoon Gauntlets, which upgrades Jump to Double Jump, which does more damage and executes faster.
While Kain cannot cast any magic in Final Fantasy IV, the data in the SNES version contains a two-frame animated sprite for Kain casting spells, as all other spellcasters have. The Final Fantasy IV Settei Shiryou Shuu shows a screenshot of Kain with a White Magic command, and there is an unused empty magic spell list that based on the internal character order, was intended for him.
Kain can equip all spears, axes, shields, helmets, Armor, gloves, and most swords and rings. In the Advance and Complete Collection versions he acquires his ultimate weapon, Abel's Lance, from the Lunar Bahamut. In all other releases, Kain's strongest exclusive weapon is the Holy Lance.
Kain appears as the Dragoon in the scripted battle with Cecil in Final Fantasy IV at Fabul's crystal chamber.
As the Hooded Man, Kain has overall decent stats in the physical department, but lacks any special abilities. Kain's HP and MP growths as the Hooded Man are different from the ones assigned to his Holy Dragoon form, and if the player wishes to get the most out of these stats they should leave him at the lowest level possible for his transformation, though this means they must complete Ceodore's Tale with Kain KO'd for much of it.
However, because only his HP and MP are affected by when he changes class, it is always possible to adjust for lost HP and MP using the HP and MP increasing items. As a Holy Dragoon Kain has high HP, Strength, Speed and Stamina, but mediocre MP.
- Kain's HP and MP as a Holy Dragoon change depending on his level when he class changes. The following stats assume he only begins gaining levels after the class change.
Kain regains the Jump ability when battling Dark Kain, and when defeating him becomes a Holy Dragoon. He knows a handful of White Magic spells after his class change and cannot learn any more as he levels up.

As a Holy Dragoon, Kain can equip the same weapons and armor as previous games, but now he can equip the Paladin-exclusive equipment as well.
Kain is faced as a boss in some cinematic battles in flashbacks at the end of the Lunarian's Tale. In each of these battles the player's actions mean nothing, after a few turns the battles end in dialogue sequences and the enemy party nor the player can be KO'd in that time.
