Summon the Villain: Marvel.

Kate Bishop stood in front of the castle's door, she looked around, feeling the mysterious atmosphere of the castle. She knew that this was the residence of her teammate Billy Kaplan, although she didn't know why Witch didn't live in the New York villa recently, but it didn't matter. Now she was eager to know more about the world destroyer.

She knocked gently on the castle's door, and after a moment, the door slowly opened, revealing Billy Kaplan. Billy's eyes showed a hint of surprise, and he obviously didn't expect Kate to come to him.

\"Hey, Kate, you're here. What's up?\" Billy asked with a smile.

\"Well, yes, Billy, I have something I want to ask you. What do you know about the World Breaker?\" Kate asked bluntly.

Billy's expression became solemn, he sighed softly, and motioned Kate to enter the castle. Kate followed him into the spacious living room, where various mysterious objects and books were placed, and some ancient paintings were hung on the wall.

\"World Destroyer, this is a dangerous existence. They are beings that span multiple universes, and their goal is to destroy the balance and cause the multiverse to fall into chaos. Our universe is no exception.\" Billy explained in a deep voice.

Kate frowned, and what she heard made her even more worried. She had heard from her father how important the balance between the universe was, and once it was destroyed, the consequences would be disastrous.

Billy went on to explain: "World Destroyers have great power and influence. They can interfere with the texture between universes and even cause space cracks. This will cause information and energy between universes to intersect, causing unpredictable consequences. In order to maintain the balance of the universe, we must stop the actions of World Destroyers."

Kate's heart was heavy. She knew it was not an easy task, but she did not intend to back down. She held her bow tightly and said with a firm expression: "I understand. We must stop them. Do you know the specific plan of the World Destroyer? I want to know more details."

Billy nodded, his eyes full of determination: "Of course, didn't I send you some information about his appearance?"

"Yes." Kate nodded heavily, and then said something that made Billy frown slightly: "The opponent is very strong. Tommy, Cathy, and Teddy were all injured by the opponent."

"What about the other party?" Billy asked tentatively.

"From what the three of them said, it seems that the other party has not suffered serious harm, but it is expected that he will stay out of the spotlight recently and carry out his evil plan in secret." Kate speculated as if thinking.

Billy listened to Kate's words, his gentle face smiled slightly, and he said confidently: "Don't worry, I already have the magic to find the other party's position. After I am familiar with it, we Avengers will assemble and defeat this evil world destroyer together."

Kate nodded in agreement. She felt Billy's determination and confidence, and also felt her responsibility as an Avenger. The exchange between the two of them made Kate more determined. She decided to work with her teammates to stop the world destroyer's plan and protect the balance and peace of the universe.

Billy Kaplan looked at Kate Bishop, his eyes full of expectation and trust.

"We will succeed, Kate. As long as we work closely together and trust each other, we can overcome all difficulties. No matter what we encounter, we will not be alone." Billy encouraged.

Kate nodded and smiled, feeling Billy's encouragement and support. She knew that as Avengers, they had the responsibility to protect the universe, and they would overcome all difficulties through unity and courage.

After sending Kate away, Billy Kaplan's face darkened. He stood in front of the castle window, looking at the scenery in the distance, but his heart was full of contradictions and anxiety. Nathan Hawke, the self-proclaimed destroyer of the world, was actually just a fabrication by him. Billy understood that he used this to deceive the Avengers and direct their attention, so as to achieve his ulterior motives.

He sighed deeply in his heart. This plan was necessary for him, but it also made him feel guilty. As a member of the Avengers, he should have shared the truth with his teammates, but for his own purposes, he had to choose to conceal it.

Billy returned to his seat, his heart full of conflicting emotions. He knew that he did this for his own purpose, but deceiving his teammates made him feel extremely heavy. Just as he was lost in thought, an evil voice sounded, interrupting his thoughts.

\"Billy, you've done a great job. You've successfully guided the Avengers into your plan. Their focus on Nathan Hawke has allowed you to act secretly behind the scenes.\" The voice was full of conspiracy and intrigue.

Billy pursed his lips. He was familiar with the owner of this voice. Kaluu, this evil being had always been his partner. For some purpose, they had reached an unspeakable tacit understanding.

\"Yes, Kaluu, I know. But I want you to assure me that it's worth it. They are my friends and I don't want to hurt them.\" Billy's voice revealed a hint of uneasiness.

\"Don't worry, Billy, everything is for a greater power. Your friends will eventually understand that their efforts will not be in vain." Kaluu's voice was full of promises and threats.

Billy's conflicting emotions become more complicated in the face of Kaluu's words. He knows that what Kaluu said is not groundless, but his inner moral entanglement cannot be ignored. In this secret collaboration, he can't help but think of his mother, whose death has a profound impact on him.

\"Billy, do you miss your mother? You know, as long as you kill Nathan Hawke, I can let you see her and reunite with her. Your strength will be far beyond what you can imagine at this moment, and all this will only cost a little bit.\" Kaluu continued to seduce.

Billy closed his eyes, his heart was in turmoil. His mother's death was a trauma that could never be healed, and what Kaluu promised seemed to ignite the desire in his heart in an instant.

\"But that would mean betraying my friends, lying to them, and maybe even hurting them. I don't know if I can do that.\" Billy's voice was struggling.

\"Billy, you have to think clearly. Your mother's existence is your eternal dream, and the Avengers are just a part of your journey. Your choice will determine your future and your mother's fate.\" Kaluu's voice became deeper and colder.

Billy was caught in an inner struggle, he knew he was standing at a crossroads, facing a very difficult decision. His heart was full of contradictions, the image of his mother and the friendship of his friends were intertwined, making him feel unable to make a choice.

"Besides, you can't turn back." Kaluu said gloomily: "Stephen Strange is now sealed in the space crack of the castle by your reality magic. As long as Nathan Hawke dies, the problem of space crack will not be a problem, and your wish to see your mother will be easily realized."

Billy exhaled, and finally made up his mind and said, "You didn't touch Tommy?"

"Haha." Kaluu laughed and replied, "Of course, you are my partner. I will not cooperate with your brother while cooperating with you. Don't worry."

Kaluu continued, "You should hurry up and learn the spells in the remaining copy of the Dark Book. I have a feeling that you and Nathan Hawke will have a battle. The necromancy magic in the remaining copy plus your real magic can definitely be combined into a new and powerful magic."

"By then, no one will be able to stop you. Even Iron Man can't stop you."

Billy Kaplan ignored Kaluu's empty promises. He had a bad feeling in his heart. This was a defense mechanism produced by his body after he learned real magic.

"It looks like someone is coming." Kaluu said suddenly, and then there was no sound.

Billy also heard the sound. It was the sound of Kang rushing over in the nano armor.

Billy Kaplan's heart tightened. He knew that Kang's arrival meant that the Avengers might have learned some intelligence, and he had to face his own concealment and deception. His heart once again fell into contradiction and anxiety, and he felt an unprecedented pressure.

In the living room of the castle, Billy quickly sorted out his emotions and tried to hide his inner uneasiness. Iron Boy's nano armor slowly landed, and the armor mask opened, revealing Kang inside, with a hint of worry and doubt in his eyes.

Billy Kaplan stood up and faced Kang who entered the castle. He tried to remain calm, but he could not hide his inner uneasiness. He knew that he was facing a serious situation and needed to deal with the doubts and concerns of the Avengers.

Kang approached Billy and looked at him. It was obvious that he felt that the situation was unusual. Kang said, "Billy, we just heard some information about the World Destroyer from other team members. However, we also noticed that you seemed a little unusual. Is there anything you didn't tell us?"

Billy Kaplan shook his head, trying to keep himself calm. He knew that the Avengers must have noticed his unusual behavior, but he couldn't easily reveal his true intentions. He looked at Kang and smiled, "Kang, I understand that you are all worried about the threat of the World Destroyer, and so am I. I was just studying some intelligence about them before, so I may have seemed a little skeptical."

Kang frowned, not seeming to be completely convinced, but he did not ask any more questions for the time being. At the same time, Wang used the portal according to the landmark Kang gave him, and appeared in Billy Kaplan's living room with Nathan Hawke.

When Nathan Hawke appeared in the room, Billy frowned. He knew that the critical moment had come and he had to implement his plan as soon as possible. Nathan Hawke's arrival made the situation more complicated, but it was also this opportunity that gave Billy a chance to break through.

After making a decision in his heart, Billy's eyes became firm. He looked at Kang, Wang and Nathan, took a deep breath, and then suddenly stretched out his hand to draw a rune in the air, while whispering a spell.
