daedalus (fate)
Berserker-class Servant introduced in Fate/Grand Order's Mystery House Crafters event. The legendary craftsman from Greek Mythology who created the Labyrinth that contained the Minotaur, and the creator of the mechanical wings used by him and his son Icarus.
The mechanical girl seen with him as a servant is not actually Daedalus, but rather Naucrate; Daedalus himself is actually the large mechanical arm. He is normally unable to communicate outside of hand gestures and beeping noises, but Naucrate acts as his translator.
