Leprechaun 4: In Space

On a remote planet in 2096, the Leprechaun courts the alien princess Zarina and proposes marriage as part of a long con. Both secretly intend to kill the other after the wedding night to secure their desired benefits—the Leprechaun's crown, and Zarina's inheritance of his gold and jewels. The arrangement sets the stage for a deadly game of political and personal ambitions.

A platoon of space marines lands to disrupt mining operations and confronts the Leprechaun on the planet's surface. In a brutal confrontation, the marines kill the Leprechaun as he tries to manipulate the situation to his advantage. The surface battle marks the apparent end of the Leprechaun's immediate threat on the planet.

Lucky makes a last-ditch attempt to steal the Leprechaun's gold. He is killed by the Leprechaun using a lightsaber, cutting his plan short. The lure of gold remains a driving motivator for later events.

A grenade explodes and seemingly finishes the Leprechaun off during the chaos on the surface. Kowalski then urinates on the Leprechaun's body in a grotesque post-battle display. The dead Leprechaun's spirit will later awaken in a surprising way.

In a bizarre twist, the Leprechaun's spirit travels up Kowalski's urine stream and into his penis, where the entity begins to manifest. The marines depart unaware of the haunting presence they've left behind. This event foreshadows the monster's return as a physical threat.

The marines return to their ship with the injured Zarina, intending to take her home and establish diplomatic relations. The mission's political veneer grows as a back-channel goal surfaces. Zarina's fate will soon be tied to the ship's experiments.

On the ship's lab, Dr. Mittenhand explains his plan to use Zarina's regenerative DNA to recreate his own mutilated body. He envisions becoming a superior, self-repairing creature through Zarina's genes. The revelation foreshadows a technological horror lurking aboard.

The Leprechaun violently emerges from Kowalski's penis after he is aroused during a sexual act. The crew realizes the threat is not dead as the entity resurfaces in a new, terrifying form. The ship becomes a hunting ground for a monster that cannot be killed by conventional means.

The marines pursue the Leprechaun through the ship, but he outsmarts them and cuts down many crew members in gruesome, absurd ways. The ship becomes a battleground between human soldiers and a resurrected fiend. Trust and discipline erode as fear spikes.

While pursuing Zarina, the Leprechaun injects Mittenhand with Zarina's DNA and the remains of a blended scorpion and tarantula. He then initiates the ship's self-destruct sequence to erase evidence and escape. Mittenhand begins to mutate, foreshadowing his monstrous transformation.

Sticks rushes to the bridge to defuse the self-destruct but is met with a password prompt and a trap. Mittenhand mutates into Mittenspider and entangles Sticks in a giant web. The crew is left scrambling to survive the cascading threats.

The surviving crew confronts the Leprechaun in the cargo bay and, after being shot with Mittenhand's growth ray, the creature transforms into a giant. The ship's crew fights for their lives against a towering foe, turning the vessel into a gladiator arena. The threat level peaks as the monster dominates the space.

Tina Reeves escapes to the bridge and sprays Mittenhand with liquid nitrogen before shooting him. She frees Sticks from the web and restores some morale to the crew. The tide turns in the humans' favor as the immediate threat recedes.

Books opens the airlock, blasting the giant Leprechaun into space where it explodes. The crew realizes the password is 'Wizard', a sly reference to Mittenhand's Oz comparison. Books and Reeves share a kiss as Sticks watches the Leprechaun's giant hand vanish into the void.
