Resurrection:
- Wormtail, a loyal Death Eater, performs a ritual involving Harry's blood, Wormtail's severed hand, and a bone from Voldemort's father in an old graveyard to resurrect Voldemort.
- Lord Voldemort regains his physical form, and his supporters (Death Eaters) gather around him.
Impersonating Alastor Moody:
- Voldemort's loyal Death Eater, Barty Crouch Jr., uses Polyjuice Potion to disguise himself as Alastor Moody, the Defense Against the Dark Arts professor at Hogwarts.
- Crouch Jr./Moody uses his position to manipulate events leading to the Triwizard Tournament and ensures that Harry's name is put into the Goblet of Fire.
Control over Harry:
- Voldemort's ultimate plan is to restore his full power and eliminate Harry once and for all.
- Throughout the tournament, tasks designed by Crouch Jr. aim to weaken or distract Harry, making him more vulnerable to Voldemort.
Return to Full Power:
- The Third Task of the tournament leads Harry and Cedric Diggory to a graveyard.
- Wormtail helps in transforming Harry's blood (which contains Lily's protection) into a potion. Voldemort drinks this potion, regaining his full power.
- Voldemort engages in a duel with Harry, but due to their unique connection (they both share the same wand's core), their spells create the "Priori Incantatem," which conjures visions of past spells and people closely associated with their wands, including Harry's parents.
Ministry Refusal and Death Eaters Revealed:
- Voldemort declares his grand reappearance to wizarding society and challenges the Ministry of Magic and Dumbledore.
- The Ministry refuses to accept Voldemort's resurrection and continues to view Harry's claims as fabrications.
- This event highlights the ongoing conflict and denial within the wizarding community about Voldemort's return.
In the end, Harry escapes and returns to Hogwarts with the help of Albus Dumbledore. Despite the skepticism of the Ministry, the events in "Harry Potter and the Goblet of Fire" pave the way for the confrontation and escalating conflicts between Voldemort and Harry in the subsequent films.
