Oddly, despite having a unique name and face among enemy units, Heimler cannot be recruited, does not not have a background story, nor has any spoken lines when he is attacked or defeated.
Heimler 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 on most difficulties, but his stats and equipment allow him to easily wipe out any weak unit.
In the DS version, Heimler drops a Master Seal when defeated.
- In the NES version, Heimler doesn't open the gate he is behind and instead waits until a unit comes close to him.
- While removed in the book 1 portion of Mystery of the Emblem, a soldier with similar stats and a Silver Lance appears in Heimler's place. Heimler's character ID also appears within the game's data and is unused like the other cut bosses.
Himmler is best known as the surname of Heinrich Himmler, a leading member of the Nazi Party of Germany and one of the most powerful men of that country. The stigma associated with the surname may have been why Heimler's name was slightly altered in international releases.
