AUTHOR'S NOTE:

Hey guys! Welcome to this new story of the Phantom Twins series! Danielle's hair was inspired by the way Natasha Romanov had done her hair in Avengers: Endgame and also the new costumes for Danny, Danielle, Dale and Dayla were inspired by Hawkeye, Scarlet Witch and Black Widow from the Avengers movies. Just a heads up, if you haven't seen Endgame, sorry if I spoiled what her hair looks like.

Anyway, enjoy the story guys

"STOP! Hold it right there!" The voices of Dani and Dale could be heard inside the Amity Park Museum as the alarms blared.

In the middle of the paranormal section, a glass case that once held a book was now missing. Down the halls, Dani and Dale Phantom were chasing after Venelope Hawkeye, or as she is known in her ghost form, Vladia Plasmius.

Sixteen year old Dani and Dale Phantom had changed over the past few months since their older siblings, Danny and Dayla had left for college. Dale when he was in his human form, wore a black leather jacket with a white t-shirt, blue jeans and black converse shoes and Dani when she was in her human form, wore a teal coloured t-shirt underneath a dark green drawstring crop hoodie, blue jeans and black converse shoes.

Even though Dale's hairstyle stayed the same, Danielle had made a change to her hairstyle. Her hair length was the same, but this time, she not only allows her hair to flow freely instead of tying it up, at the ends of her flowing hair, she had white highlights and when she changed into her ghost form, the ends of her white hair were black.

Their ghost form outfits had also made a change. Danielle's costume, the black top part with white DP logo in the middle, dark green leather jacket that reached down past the back of her thighs. The pants were white with black boots that reach up to her knees and now wears short white gloves.

With Dale's costume, the top part of his suit was now sleeveless and he now wears short white fingerless gloves. The top part of the suit was now white with his DP symbol that was in the middle now black. His pants were black and now both his boots were white.

The reason they were chasing after Vladia Plasmius at the museum? Dani and Dale had been on their nightly patrol with their team mates and also boyfriend and girlfriend, Jimmy and Sonya when the daughter of Vlad Masters had triggered the alarm at the museum. In her hands was the book titled, Legendary Artefacts of the Ghost Zone. The exact same book that used to belong to Vlad Masters, which had information of many legendary objects that are part of the Ghost Zone, including the InfiMap.

After Vlad Plasmius was left behind in space, the FBI, CIA, police and Jack and Maddie Fenton had searched his mansion. Finding the book, Jack and Maddie had held onto it for a while before giving it to Alfred Grant, the owner of the Amity Park Museum, who had opened the new Paranormal Wing as a tribute to Danny, Dayla, Danielle and Dale for all their heroics in Amity Park and the world.

It had become a great tourist attraction for Amity Park, giving more insight about the Ghost Zone to everyone. Team Phantom happily shared everything they had discovered and researched about the Ghost Zone and even introduced Alfred to some of their ghostly allies who also shared their world with people.

After Venelope discovered the book had belonged to her father, she decided that she would steal it for herself, believing she may find something useful to help her in her quest for revenge against Team Phantom once and for all.

"Guys, have you got the trap ready outside?" Dale asked quietly through his Fenton Phone.

"We're ready out here. The police are waiting as well." Sonya's voice replied.

"Fifteen seconds guys." Dani instructed through her Fenton Phone.

They continued to follow Vladia, heading for the front doors of the museum. Vladia turned intangible and as soon as she phased through the doors, Dani and Dale both shouted through the Fenton Phones, "NOW!"

Jimmy and Sonya sprang from the two bushes outside the building, wearing the special jumpsuits Jack and Maddie had made for them, back when they first battled Vladia Plasmius and fired their bazookas. Vladia gasped as she was ensnared by two ecto nets and crashed into the pavement. Police held their guns pointed at Vladia as Dani and Dale phased through the doors and landed in front of the now trapped Vladia Plasmius.

"It's over Vladia, return what you stolen and turn yourself in." Dani said, crossing her arms.

"Why did you want that book anyway?" Dale asked.

"As if I'd tell you. Not a bad plan you two by the way, but what makes you think I'm actually here? I'm already gone." Vladia said with a smirk.

"Gone out of your mind, that's for sure." Jimmy said, glaring down at her. "There's no way that you can escape this time."

She continued to smirk and then suddenly, she faded away, making them all gasp in shock. Dale knelt down to where she was and punched the ground with a groan of frustration.

"Another duplicate." Dale said as he stood back up. "One thing's for sure, she's definitely an expert of avoiding being captured."

"Now she's gotten away with that book Vlad used to own." Dani said, looking down. "Who knows where she's hiding now?"

"Hey guys. Come on. It'll be okay. We'll stop her someday." Sonya said, trying to cheer them up with a pep talk. "We've overcome many obstacles in the past and stopped all of her schemes. Whatever she's up to with that book, we'll be ready and we'll have help from the rest of Team Phantom as well."

"She's right guys. We'll handle Venelope and we'll do it together, just like we always have done." Jimmy added.

Dani and Dale smiled at their partners and hugged their boyfriend and girlfriend, feeling so lucky to have met them. They turned to the sound of a cars parking and saw Alfred Grant coming out of one of the cars and the others, belonging to news reporters and members of the press.

Dani, Dale, Sonya and Jimmy walked up to him. Dani then spoke, "We're sorry Mr Grant. The good news is that nothing else was stolen except for the book. The bad news is that Vladia Plasmius managed to escape."

"It's alright Team Phantom. Thank you anyway for stopping her from stealing anything else." Mr Grant said with a grateful smile. "What I don't understand is what she wanted from that book?"

"We wish we knew, but we'll investigate and hopefully find out." Dale said.

A few minutes later of answering questions to the press about what happened, Team Phantom called it for the night and returned to their homes. Dani and Dale were excited since the next morning, Danny, Dayla, Sam, Tucker, Valerie and Andrew were coming home back to Amity Park for their college semester break.

Jazz had arrived in Amity Park that morning and all of them shared the excitement of the rest of Team Phantom returning. They had hoped that their semester break would be a little bit ghost free, but now with Vladia Plasmius up to something once again, it looks like it wouldn't be entirely ghost free after all.
