LooneyAces here with the fourth story of the Danny Phantom/Marvel Cinematic Universe crossover series, and the start of Phase 3. Danny will also have a new outfit, which is on the cover photo. I do not own Danny Phantom and related characters. They belong to Butch Hartman and Nickelodeon. I also do not own the Marvel Cinematic Universe and its characters. They belong to Marvel Studios. Anyway, on with the story.

Prologue: Siberian Overture.

In the year of 1991, at the HYDRA Siberian Facility in Siberia, of the Soviet Union, where a group of HYDRA operatives, inside the Soviet, soon to be Russian, Armed Forces does their operations there, Russian Colonel and HYDRA operative Vasily Karpov types in a code before a small door opens to reveal a red book with a black star on the cover. He then revived a person from a cryostasis chamber. The person is known as James Buchanan 'Bucky' Barnes, a former soldier of the US Army and the childhood best friend of the war hero known as Captain America. Unfortunately, he was thought to be killed during a fight on a HYDRA train back during the war. In reality, he actually survived, albeit with the loss of his left arm. Brainwashed and armed with a new cybernetic limb, Barnes ultimately became an enhanced HYDRA operative known as the Winter Soldier. Over the next several decades, he would eliminate anyone who posed a threat to HYDRA. Anyway, Karpov has revived Bucky and, along with other HYDRA operatives and scientists, subsequently put him under the Memory Suppressing Machine to wipe his memories and emotions. During Bucky's brainwashing session, Karpov is reading the red book to trigger and activate the Winter Soldier.

"Toska. Rusted. Semnadtsat'. Daybreak. Pech'. Devyat'. Dobrokachestvennaya. Vozvrashcheniye domoy. Odin. Gruzovoy avtomobil'." ("Longing. Rusted. Seventeen. Daybreak. Furnace. Nine. Benign. Homecoming. One. Freight car.") Karpov read.

There was only silence as Bucky looks at Karpov closing the book and sets it at a nearby table.

"Dobroye utro, soldat." ("Good morning, Soldier.") Karpov greeted.

"Gotov otvechat'." ("Ready to comply.") Bucky said.

"U menya dve missii dlya vas. Oba sanktsii i vypisku. Nikakikh svideteley." ("I have two missions for you. Both sanction and extract. No witnesses.") Karpov ordered.

Bucky is currently on his first mission of the day in the state of Minnesota. He was sitting on a motorcycle waiting for his target. It is currently dusk and the road shows no cars, so no witnesses would be presented. Suddenly a car passes by. Bucky knows that this particular car is going to the Pentagon in Washington D.C. Bucky turns on his motorcycle and proceed to intercept the vehicle. Bucky then drove his motorcycle to the side of the moving car before hitting it with his metal arm, causing the driver to loose control of the car and crashed at the back of a large sign that says...

'Amity Park: A Nice Place to Live!'

Bucky then turn his bike around before stopping next to the crashed car and proceed to kill the car's occupants before opening the car's trunk and taking a briefcase that was inside.

Bucky is now on his second mission of the day, hiding at a wooded area next to a road at Long Island, New York, and it is dark outside. Just like his first mission, no witnesses will be presented. Suddenly, Bucky sees another car passing by. Bucky knows this car is also on its way to the Pentagon in Washington D.C. Once again, Bucky turns on his motorcycle and proceed to intercept the vehicle. Bucky then drove his motorcycle to the side of the moving car before hitting it with his metal arm, causing the driver to loose control of the car and crashed into a nearby tree. Bucky then turn his bike around before stopping next to the crashed car and proceed to kill the car's occupants before opening the car's trunk and taking another briefcase that was inside.

Bucky arrived back at the HYDRA Siberian Facility with the two briefcases to deliver to Karpov. Bucky then open the two cases. One case shows five blue packets of the Super Soldier Serum, the same serum that created Captain America back in the 1940s. The other briefcase contains multiple files that shows the research on the Super Soldier Serum and a book that shows files and research on a half human-half ghost hybird theory called the Halfa Theory. Karpov is impressed with Bucky's mission success.

"Molodtsy soldata." ("Well done Soldier.") Karpov said.

However, these two events is just the beginning.

And that's the end of this chapter. Now, what was Bucky doing in Amity Park? And who did he kill? You'll find out later in this story. I hope you all will enjoy this story. Anyway, please review.
