Edge is a Ninja, allowing him to dual wield weapons. Edge's abilities include Throw, which allows him to throw weapons at his opponents for high damage; Steal, which allows him to steal items from his opponents; and Ninjutsu, which allows him to cast special Ninja spells. In the Advance and Final Fantasy IV: The Complete Collection releases, Edge gains the Hanzo Gloves for completing his Lunar Trial that upgrades Steal to Plunder. With Plunder, Edge will attack if he successfully steals. In all versions of the game save the 3D remake release, Edge takes some damage if he fails to steal an item. In the remake release Edge learns more Ninjutsu skills.
Edge and the Eblan Four have a level cap of 40 in his chapter. Edge has all around decent stats with the exception of his low Spirit, and while he is primarily a physical attacker he can be a somewhat effective Black Mage with Ninjutsu. Edge's greatest asset is his high Speed, and he is the second-fastest character in the game after Tsukinowa.
Edge retains his Ninjutsu techniques, and learns a much larger variety of them than his apprentices do. He also has the Throw ability and Mug (Smash & Grab in the WiiWare version), which lets him attack enemies and attempt to steal from them.
Edge's equipment has expanded in Final Fantasy IV: The After Years. The most significant item is Rubicante's cloak, the Fire Scarf. It provides adequate Defense and can absorb all Fire-elemental attacks and when combined with a Protect Ring can give him absorption to Ice and Lightning additionally.
