Dante encounters Trish again, only to discover that she has been working for Mundus all along. She deceives him and tries to kill him, but he manages to survive. However, when he sees her in danger, he does not hesitate to rescue her. He tells her that she reminds him of his mother, who died protecting him from Mundus. He asks her to stay behind while he goes to face Mundus alone. But as he reaches the final showdown with the Demon Emperor, he finds Trish in his way. She was part of Mundus's plan to weaken Dante's resolve and make him vulnerable. Mundus attacks Trish with a powerful blast, but Dante shields her with his body and gets wounded. Mundus prepares to finish them off, but Trish sacrifices herself and blocks the attack with her own body. Dante is overcome with grief and anger, and unleashes his full potential as the son of Sparda. He breaks free from the statue that was holding him back and confronts Mundus in his true form. Mundus creates a dark dimension around them and flies up to the sky. He taunts Dante by saying that he can create anything he wants, including Trish, who was nothing but a puppet for his scheme. Dante defies him and tells him to shut up. He follows him to the sky and transforms into Sparda's form as well. The epic battle between the two begins.
The battle is fierce and intense, as Dante and Mundus exchange blows and blasts. Dante uses his sword and guns, while Mundus uses his claws and beams. They both unleash their demonic powers, creating shockwaves and explosions. Dante is determined to avenge his mother and brother, while Mundus is determined to destroy the last threat to his rule. They fight with all their might, but neither can gain the upper hand.
Meanwhile, Trish regains consciousness and sees the fight in the sky. She feels a surge of emotion for Dante, who saved her twice despite her betrayal. She realizes that he has a heart of gold, unlike Mundus who has a heart of stone. She decides to help him, even if it means defying her creator. She grabs the sword Sparda, which was left behind by Dante, and flies up to the sky. She joins Dante in the fight against Mundus, surprising both of them. She tells Dante that she is sorry for what she did, and that she wants to fight by his side. She tells Mundus that he is wrong about her, and that she has a will of her own. She gives Dante the sword Sparda, which boosts his power even more.
Mundus is enraged by Trish's betrayal and tries to kill her again. He fires a massive beam at her, but Dante blocks it with the sword Sparda. He tells Trish to stay back and let him handle Mundus. He tells Mundus that he has gone too far, and that he will pay for his crimes. He charges at Mundus with the sword Sparda, ready to deliver the final blow.
Dante and Mundus clash with the sword Sparda, creating a huge explosion. The dark dimension begins to collapse, and the two fall to the ground. Dante lands safely, but Mundus is severely injured. He crawls to Dante and tries to grab him, but Dante kicks him away. He tells Mundus that he has lost, and that he should give up. He tells Mundus that he is nothing but a tyrant, and that he will never rule over anyone again. He tells Mundus that he is not his father, and that he will never be like him.
Mundus refuses to accept his defeat and vows to return. He tells Dante that he will never forgive him, and that he will always hate him. He tells Dante that he is his enemy, and that he will always be his enemy. He tells Dante that he is not his brother, and that he will never be like him. He summons the last of his power and opens a portal to the underworld. He drags himself into the portal, swearing revenge on Dante.
Dante watches as Mundus disappears into the portal. He feels a mix of relief and sadness, as he has finally avenged his family, but also lost his only connection to his father. He wonders if he will ever see Mundus again, and if they will ever reconcile. He turns to Trish, who is waiting for him. She smiles at him and hugs him. She tells him that he did it, and that he is amazing. She tells him that she is proud of him, and that she loves him. She tells him that he is not alone, and that she will always be with him. She tells him that he is her hero, and that he will always be her hero. 061ffe29dd
