“Hahahaa... Alright, let's do this. Finally, a chance to kick some ass.”
—Lex, heading into battle in Genealogy of the Holy War
Lex (レックス, Rekkusu, Rex in the Super Tactics Book) is a character from Fire Emblem: Genealogy of the Holy War. He is the son of Langobalt, the duke of Dozel, and the half-brother of Danan. He is a possessor of minor Neir blood, and is widely regarded to be a rebel to his family's name. Lex is an Axe Knight who fights for Sigurd, and is the childhood friend of Azel and Tailto.
Lex's makes his first appearance in the Prologue, in which he appears from the north alongside Azel on the second turn. He is hot-headed and loves to fight, but as a result of Genealogy of the Holy War's weapon's system, he can usually only attack once. However, by standing on a certain space with an Iron Axe in Chapter 1, he will receive a Brave Axe from a mysterious woman of unknown origins.
Lex will eventually perish in the Battle of Belhalla, alongside a good number of his fellow comrades.
Lex is the only character in the first generation who is able to wield axes before promotion. As a result of possessing the Elite skill, alongside being able to lay claim to a Brave Axe, he is thus a very useful unit to be trained indeed. If given sufficient training, Lex will usually promote by the time Chapter 4 begins.
Lex is best paired with Ayra, Briggid, or Tailto. The only problem that will arise from his pairings is that he will be unable to pass down any of his weapons to his possible sons, owing to the fact that they are not axe users by nature.
Fire Emblem Treasure's family tree, which previously revealed that Lex and Danan had different mothers, also stated that Lex had another older half-sibling. As the name is faded on the chart, this sibling is presumably dead.
The Hero Axe conversation is a reference to one of Aesop's fables, The Honest Woodcutter.
