Ash and his Pikachu, along their companions, Misty and Brock were in Cianwood City after Ash had won the Storm Badge from the Cianwood City gym trainer Chuck. They were on their way to the docks to wait for a ferry to the mainland, when suddenly as they passed by a Pokemon Center, Nurse Joy came out of the building and stopped them.

Nurse Joy then said to Ash, "Excuse me, there is a phone call for you from a Professor Oak in Pallet Town."

Ash and his friends then walked into the Pokemon Center and went over to one of the video-phone stalls.

The screen revealed Professor Oak, feeling content to see Ash and his companions, started speaking, "Hello there, Ash, it's good to see you again, as well as your friends."

Ash then asked, "So what did you call us up for?"

Professor Oak replied, "I wanted to tell you that I want you and your friends in Pallet Town as soon as possible."

Misty asked, "Why? Is there something wrong?"

Professor Oak replied assuring her, "No, young lady, nothing is wrong. I just have something very important that I want the three of you to see."

Brock asked out of curiosity, "What is it?"

Professor Oak's response was, "You'll have to come to Pallet Town to see."

The video-phone screen then went blank as he hung up, leaving Ash and his friends mystified, but they knew that they couldn't refuse Professor Oak's request and unanimously agreed that they should head to Pallet Town, post haste.

And sure enough, Ash and his friends made it to Pallet Town within 2 days, and Professor Oak was expecting them at the Pallet Town's Pokemon Center. He quickly led them inside and into a room which had six other individuals who were as old as Ash and his friends. Ash, Misty, and Brock sat at a table where the six individuals were also sitting, as Professor Oak stood next to a projector screen.

Professor Oak stated, "Before we start, I want to introduce you to each other. Ash, Misty, Brock, these are Lance, Laurel, Pika, Charles, Skyler, and Burke. And everyone, this is Ash Ketchum and his friends, Misty and Brock. Now, I shall enlighten you all on why I summoned all of you here. Last week, I was using a space telescope to observe a helium gas cloud being devoured by a black hole. Here is an animation of the black hole in particular, the supermassive black hole at the center of our Milky Way galaxy, Sagittarius A*."

With said, a computer animation of the supermassive black hole, Sagittarius A*, appeared on the projector screen. Everyone sitting at table gasped at the sight of the black singularity surrounded by a spinning, heated, accretion disk.

Laurel then said with shock, "It's like a scene out of Dante's Inferno."

Ash then said with awe, "Yes. The most destructive force in the universe. Nothing can escape it, not even light."

Misty added, "I read in an article by Professor Birch from the Hoenn region that one day black holes would devour the entire universe."

Brock then said, "Why not? When you can see giant suns get sucked in and disappear without a trace."

Pika said, "Everytime I hear about one of those things, I excpect to see some guy in red with horns and a pitchfork."

Lance then added, "It's a real life monster alright."

Professor Oak then stated, "A rip in the very fabric of space and time. But while I was watching the black hole devour the helium cloud, I sighted something else of interest."

Ash asked, "What was it?"

Another image popped up on the projecter screen, zoomed in closer to the black hole, but showing the outline of an object near the black hole.

Professor Oak said, "It hasn't moved since I first picked it up last week. It appears to be some kind of ship."

Charles then asked, "But how could anybody be out there ahead of us?"

Professor Oak then stated, "I decided to try and indentify the mystery spaceship through an identification program. 6 times, I failed to get a match. Then on the 7th try, I managed to identify it as the American-built Deep Space Probe One, named USS Cygnus."

Skyler then quietly asked Lance, "Hey Lance, wasn't that the ship that our creator was on before he returned to Earth in 1978?"

Professor Oak then said, "The mission that the USS Cygnus was given was to try and discover habitable life in outer space. The same as our space telescope."

Burke then asked, "What happened to that ship?"

Professor Oak replied, "Well, 35 years ago, on December 21st, 1979, the USS Cygnus and its crew were recalled to Earth, their mission was considered a failure. The mission's lead scientist was Dr. Hans Reinhardt."

Brock asked, "Did you meet Dr. Reinhardt?"

Professor Oak responded, "Collided with him would be a more accurate description."

Misty asked, "So do you think he ignored his recall?"

Ash said, "Maybe. It also could be that it never got through."

Professor Oak then said, "Well, that has remained a mystery all these 35 years, because shortly after the recall was sent out, the USS Cygnus and its crew disappeared. It had never been seen again."

Lance asked, "But do you think that anyone would go looking for them?"

Professor Oak replied, "15 years after the USS Cygnus disappeared, the National Aeronautics and Space Administration or NASA of the USA sent the deep space exploration spaceship, USS Palomino and its 5-person crew to search for the ship. But the USS Palomino and its entire crew were also never seen or heard from again."

Ash then said, "Now after 35 years of being lost in space, you managed to find the ship near a black hole with a space telescope."

Charles then asked, "So where do we come in?"

Burke added, "What do we have to with all this?"

Professor Oak responded, "Before you I called you all here, I relayed my discovery to NASA. When they recieved the news of the USS Cygnus and its location, they gave me the request to set up a team to go to the ship. I felt like choosing all of you. You may not be astronauts, but given all of your backgrounds, you are all proficient. We have a great Pokemon trainer and two experienced gym trainers. Ash, I should let you and your friends know that brother-sister duo, Laurel and Lance, and their friends are all human-pokemon hybrids."

Ash and friends became both greatly surprised and awed by this information.

Laurel then said, "What Professor Oak said is true. We were created by Dr. Fuji, this was before he made that psychic-type Pokemon clone, Mewtwo. My brother Lance is a hybrid of human and Latios DNA. I'm a hybrid of human and Latias DNA. Pika is a human-Pikachu hybrid. Charles, a human-Charmander hybrid. Skyler, a human-Squirtle hybrid. And Burke, a human-Bulbasaur hybrid."

Professor Oak then said, "Before you get into space, you need to get to the spaceport, the Cape Canaveral launch area in Florida, in the United States."

Ash, Misty, and Brock then agreed to do the mission.

Lance then said, "We'll do the mission too. But before we leave for Cape Canaveral, our friends, my sister, and I want to see if we can recruit the Pokemon my sister mentioned before. Don't worry, the 6 of us already have an idea of where he is, and given our biology, we think he'll listen more to us rather than normal humans."

Ash then said, "Then the 3 of us will wait here with Professor Oak, until you come back, hopefully with Mewtwo."

Misty said supportively, "Let's hope he can be understanding with you."

Brock added, "Either way, we'll all be involved in a mission of historical significance."

Then Professor Oak, Ash, and his friends bid Laurel, Lance, and their friends farewell as the 6 hybrids headed for Cerulean Cave to speak to Mewtwo, and see if he would join them on their mission to the center of our galaxy, its supermassive black hole, and the lost but now found USS Cygnus.
