Ozzie Jones/Original Timeline

Ozzie Jones is dimwitted and works with his friend Alex and Nathan Murphy by painting houses.

Leprechaun
Contract workers Ozzie Jones, Nathan Murphy, and his 10-year-old brother Alex help re-paint the O' Grady farmhouse. While looking around the basement, Ozzie hears the Leprechaun's cry for help and mistakes him for a little child. He brushes the old four-leaf clover off the crate, freeing the Leprechaun. After failing to convince the others that he met a Leprechaun, Ozzie spots a rainbow and chases it, believing that he will find a pot of gold at the end. Alex accompanies him for fear that Ozzie might hurt himself. A bag of one hundred gold pieces magically appears before Ozzie. After Ozzie tests the gold and accidentally swallows a piece, they stash it in an old well and plot to keep it for themselves, hoping to fix Ozzie's brain.

The Leprechaun lures J. D. into a trap by imitating a cat, biting and injuring his hand. Nathan and the others rush him to the hospital, and the Leprechaun follows on a tricycle. Alex and Ozzie visit a pawn shop to see if the gold is pure, and the leprechaun kills Joe the shop owner for stealing his gold. After leaving J. D. at the hospital, the group drives back to the farmhouse. Finding it ransacked, Nathan checks outside, where he is injured by a bear trap set by the Leprechaun.

After finding a shotgun in the farmhouse, they shoot the Leprechaun several times. When this has no effect, they attempt to flee the farm, but their truck's engine has been sabotaged by the Leprechaun. After ramming the truck with a go-kart, the Leprechaun terrorizes the group until Ozzie tells them about Daniel O'Grady, who was taken to a nursing home after his stroke. Tory visits the home to learn how to kill the Leprechaun.

After learning that a four leaf clover is the Leprechaun's weakness, Tory returns to the farmhouse, where she searches for a clover until she is attacked by the Leprechaun; Nathan and Ozzie save her. Alex sets a trap near the well, but the Leprechaun almost kills him. Ozzie reveals that he swallowed the last gold coin, and the Leprechaun critically wounds him trying to get it. Before the Leprechaun can kill Ozzie, Alex takes a four-leaf clover Tory has found, sticks it to a wad of gum, and shoots it into the Leprechaun's mouth, taking away his power. The Leprechaun falls into the well, but his skeleton climbs out. Nathan pushes the Leprechaun back into the well and blows up both the well and the Leprechaun with gasoline.

Terrified at seeing the well after 25 years, he leaves in a hurry unknowingly dropping his cellphone. When he returns to the old house to retrieve his phone, water splashes on Ozzie from the old well and he ends up swallowing some of the water and hurriedly leaves. But as he drives away in his truck he feels sick and feels something move around in his belly. He leaves his truck and ends up coughing up the four leaf clover they used to defeat the leprechaun 25 years ago. Within a few seconds the resurrected leprechaun rips its way out of his intestines.
