Nicholas "Nick" David Larson is a sixteen-year-old demigod son of Hermes.
Nick finds April passed out in the woods and takes her back to Camp Half-Blood.
He starts hitting on her, frequently using pick-up lines (April's favorite being "You look like my third wife." "Oh, how many times have you been married?" "Twice."). After she tells him about the triplets and Stefan, he is very sympathetic.
Nick kisses April, which shocks her. She didn't realize it, but she had feelings for him all along.
Nick's father, Hermes, walks in on Nick and April making out. When he says "...you and your girlfriend were going too far," they immediately insist that they are not boyfriend and girlfriend.
Nick and April get married. He acts as the "father" to her triplets, who are biologically Stefan's.
Nick and April have another baby.
Nick is 5'11 and weighs 150 lbs. He is very pale, with blonde hair and light blue eyes (like most of the Hermes kids). He strongly resembles April's ex-boyfriend, Stefan, which is one of the reasons she likes Nick but is confused about what she feels for him.
Nick is sarcastic, flirty, and reckless. He has a good sense of humor. He can be insensitive, as shown when he asks April if she is single after she mentions that her boyfriend (the father of her unborn son and daughters) left. He is a bit mysterious and may be a little moody at times.
