Full Drive (フルドライブ Furu Doraibu) is the most powerful form of a Device. Some examples of Full Drive forms include:
- Bardiche's Zanber Form and its many derived forms implemented in Bardiche Assault
- Graf Eisen's Gigantform, which drastically increases the Device's size and destructive power
- Laevatein's Bogenform, used by Signum to cast her most powerful ranged spell, Sturmfalken
- Mach Caliber's Gear Exelion, which greatly increases Subaru's mobility and combat potential
- Raising Heart's Exelion/Exceed Mode, used by Nanoha to cast her most destructive bombardment spells
In The Battle of Aces and The Gears of Destiny, this is a state in which characters gain increased attributes and can perform "Full Drive Burst" finishing moves.
