Liam the Leprechaun, or simply known as Leprechaun, appeared in Annoying Orange: Luck o' the Irish and Annoying Orange vs. FRED!!! as the main antagonist.
He was played by Bobjenz.
Liam met Orange when he lost his pot o' gold. Orange found it almost instantly, and Liam gave him three wishes. Orange got the famous whistling pinwheel, but Liam took it away because Orange was too distracted with it to make a second wish. Orange didn't want anything besides the pinwheel and a pot o' gold, and he called Liam a little giant, so Liam blew it. An offended Orange wished Liam would have his pot o' gold so he could calm down. Unfortunately, the pot landed on Liam, seemingly killing him, and the pinwheel was tooken by Pear.
Liam survived and came to get revenge on Orange. He used leprechaun magic to create an illusion so Orange could know what it's like to be annoyed. It was basically an annoying match where the two compatents annoy the crap out of each other until one can't take it anymore. Orange battles Fred Figglehorn while the real pear watched. Unfortunately, after a while, they both started screaming so loud that Liam's hypnotic powers couldn't hold up, and rubble from the stadium landed on Liam, smashing him again. Orange and Pear were returned to the real world.
In real life, Liam was teleported to the leperchaun world immediately after he appeared to be smashed, and the leperchaun boss revealed that Lian is 200 years old and that he has been losting his pots of gold over and over again. Liam was given another pot of gold, but he accidently teleported it to a grapefruit identical to the one Orange knew and with an identical personality. This Grapefruit also knew Passion Fruit. Liam granted this Grapefruit three wishes for the pot of gold: a parakeet, a date with Passion Fruit, and some weights. The weights were girly weights, as shown on the weighths themselves, but Liam didn't care because Grapefruit didn't have any arms. The date turned out to be the fruit date with a picture of Passion. Unfortunately, Liam messed up and the parakeet turned out to be an evil pteranodon called Terror-dactyl, who ate the date and stole the gold, starting a whole new series where Liam is the center character.
