Leonard "Lenny" Flynn Boyle is the secondary antagonist of Fanboy & Chum Chum. He is the manager of the Frosty Mart.
Before Fanboy & Chum Chum drove him crazy, he had a shaved haircut with sideburns. Also, he didn't have glasses.
In the Pilot short, Lenny was moderate apricot skinned and had orange-ish, much like Napoleon Dynomite. Also, he appeared to be more bulky than in later episodes.
Currently, Lenny wears a Frost Mart uniform whenever he goes. Under his uniform, he sports a pair of bluish - grey jeans, black & white checkered canvas shoes. He is dark - brown skinned, has his dark brown hairin an afro, and wears sleet black glasses.
Lenny is a very nice and sometimes bossy guy. When Fanboy & Chum Chum are around, he seems extremely bossy and mean, but when he's relaxed and alone, he's really nice and calm. He finds Fanby & Chum Chum irrtating and sometimes gets a "stress twitch".
When he first got a job at the Frosty Mart, Lenny was quirky and silly. He worked as a janitor and constantly scrubbed the glass doors, singing a song. However, it wasn't long before Fanboy & Chun Chum came in the first time came in the Frosty Mart for the first time. They were asking for directions for the library to learn to read. (i.e. discover "The Wonderful World of Reading"). But when they were represented with the Frosty Freezy Freeze, They loved it so much, they danced around Lenny, screaming "More" several times. Lenny eventually grew annoyed of them.
Now the Assistant Manager of the Frosty Mart, Lenny works behind the counter working hard, keeping watch over his employee Boog and his customers. He often gets stressed by the encounters of the customers, but calms down at times and gets it right.
- He also bears a resemblace to Michael Johnson, one of Fanboy & Chum Chum's friends.
