|Mr. Phillips Luzinsky|
|Aliases||Mr. Luzinsky, Mr. Phillips|
|First Appearance||Dexter's Rival|
|Voiced By||Frank Welker|
He is a short, round and pudgy man with a large double chin, a bald head with a little gray hair and a small nose, resembling Ben Franklin. He wears a salmon pink sweater vest over a white formal shirt along with a black bow tie, small glasses and brown pants with brown shoes.
In seasons 3 & 4, his appearance changed drastically, how having a more rectangular body shape with a large and bulbous orange nose and darker gray hair. His vest was now green and had diamond patterns.
Mr. Luzinsky seems to be a generally upright and knowledgeable teacher. His hero, apparently, is George Washington Carver. Like many of the teachers at Huber Elementary, he is very proud of Dexter and admires his intelligence. He even considers Dexter to be his official "teacher's pet", a fact which Dexter is proud of.
