Nathan is a child neighbor of Jon Arbuckle, known for making scientific projects with diabolical intentions. He is introduced as a new neighbor in his first appearance. His only known relative is his mother.

His first plot, after briefly adopting Odie, was to turn Odie into a cockroach. However, Garfield and Squeak foiled the attempt, which resulted in Nathan falling into his own trap.

He later came up with devices to change size (which Garfield deflected using a mirror), control minds (which Garfield used with a radio), create invisibility (which Garfield sprayed paint all over Nathan, causing him to get caught), and give nightmares (where Dr. Whipple appeared in Garfield's dream, and woke him up, so Garfield could get revenge), all of which he used and failed against Garfield.

He is known to be Garfield's nemesis.

He was briefly the owner of Mrs. Ferret.


Nathan is a boy with brown hair and wears glasses. In his normal clothes, he wears a dark blue shirt, a purple pants and red sneakers. In his scientist form, he wears a lab coat, headgear and blue gloves.


Nathan at first to Garfield and Odie was a nice kid but in his true form he is shown to be an evil scientist.
