Thundrakes are Lightning-elemental dragons found in Final Fantasy Tactics Advance. Possibly the strongest regular monster, its stats are higher than those of most other monsters, and it can further boost them by using its Dragon Force skill. Eventually they become extinct, as there are no Turf Defense missions or clans that they belong to.
Gerland the Magewyrm is a powerful Thundrake that like to use "Dragon Force" to boost the stats of its two Dragon underlings.
