Luke's IQ had been tested in the genius range. He has an affinity for computers and has an eidetic memory — at least up until his mother asks him to vacuum the living room, which he forgets very quickly.
- Luke works hard on his swordsmanship.
- He hates being the "baby" of the family; he's very skinny, the the point where Hunter makes him sit on the sidelines during combat scenarios.
