An archaeology teacher of Gressenheller University. Because of his brilliant mind, he's often called upon for some of the most unusual mysteries in Europe, like the mysterious Specter, the search for the Golden Apple, the curse of the Elysian Box, even the secret of Ambrosia.
Kindly and well-mannered, Layton expresses the importance of being a gentleman - for this reason, he's very considerate of others. Also, he likes to train his mind daily with puzzles and brainteasers. Since his travels often get him involved in a lot of major cases, he's often mistaken for a detective - though his intellect does help crack a number of these cases. Also noteworthy is that he's almost never seen without his trademark top hat - he even modified the roof of his Laytonmobile so that he can get in and out without having to take off his hat.
Besides archaeology, Layton is also a skilled fencer, good at anticipating attacks and countering them. Not to say he's at all great at traversing fields of ice, of course...
