Heimler (ヒムラー Himurā, Himmler in the Japanese version) is an enemy unit in Chapter 12 of Fire Emblem: Shadow Dragon and the Blade of Light and Fire Emblem: Shadow Dragon. In the latter, Heimler drops a Master Seal when defeated. He also carries a Door Key, which he will use a few turns into the battle to unlock a door and attack the player units. He has poor HP and defense, but he can easily wipe out any weak unit.
