Automaton

information copied from Leto's article 

The myth unit for Leto is a formidable and cheap one. It's like a self-repairing, very strong robot, but one with a small favor cost: the automaton, a metal man that has the special property of being able to repair itself after battle. Surviving automatons may also rebuild other automatons that were destroyed in battle, if rebuilding takes place fairly quickly. For this reason, it seems recommendable to keep automatons together and in sizable numbers (four or more) to take advantage of their special abilities. Leto also gives access to mythological improvements that make automatons less susceptible to pierce damage (arrows) and gives them more hit points.

Leto's upgrades revolve around her myth unit, the Automaton. An Automaton is a metal man that can build and repair others of its kind. They are simple and strong.
