(Hey everyone, I'd like to take a second and explain what the main premise of Quantum Leap is. Basically a scientist named Sam Becket started researching how to time travel but conducted an experiment on himself prematurely. He was sent back in time but with a twist. He "leaps" into the bodies and lives of people who had something go wrong in their life. In order to leap to the next person, Sam has to fix the problem in his current hosts' life. He is accompanied by AL, a former researcher who appears in the form of a hologram and helps Sam. Ziggy, the AI that the project used, also helps Sam and AL but from the present time.)

(So in this fanfic, I wanted to have Sam leap into the lives of main/side characters of games, movies, books, cartoons, TV shows, etc. I do not own Quantum Leap or any other media that is featured in this crossover.)

LEAP

Sam was wearing some kind of uniform with a strange pin on it. He had some kind of futuristic pistol in his hands. He was in some kind of hallway or whatever was left of one. There were multiple burn marks on the walls and at least five bodies on the ground. Two were human but the others looked alien, they were all wearing red versions of the blue shirt that Sam was wearing.

"Bones! Come on!" A human wearing a yellow shirt yelled from down the hallway.

"Oh boy." Sam whispered.

"Bones, there are still people trapped over here!" The same person yelled.

Sam ran over to the man and started helping him lift a heavy metal trust off a pile of debris.

"It'll be a miracle if the Enterprise makes it threw this one!" The man uttered while digging through the rubble.

The pair eventually found a man who had been buried and took him to what Sam assumed was the sick bay. The room was obviously very busy as all the beds and even some floor space was occupied by injured personnel. Sam stepped back into a corner where AL was standing.

"AL where am I?" Sam asked the hologram.

"Okay, Ziggy says you're on a space ship called the Enterprise. You are the chief medical officer, Dr. Bones. The ship was just attacked by an alien race known as the Klingons. That guy who you brought the injured crew member down with is Captain James T. Kirk, and at some point over the course of the next three hours, he gets murdered." AL said.

"A space ship! Aliens!" Sam freaked out.

"Yeah, when you last leaped, you hit some kind of temporal current and got sent into the future. Ziggy also plugged into it and that's how we got this information." AL said.

"Okay, so my job is to prevent the Captain from getting murdered. Simple enough, I'm the ship's doctor." Sam said before walking over to Kirk.

"Captain, mind if I take a look at that scrape?" Sam asked the captain who was bleeding from his forehead.

"Don't bother Bones, it's just a scratch. There are other people who need it more than me." The captain said.

"No really, I insist." Sam said.

"Fine, you're the doctor." Kirk said before following Sam to an examination table.

Sam looked at the cut and also noticed that the captain's eyes were dilated. Upon further tests and scans, Sam determined that Kirk had been hit by a blunt metal object that had caused a concussion.

"Okay you have a laceration and it's deep. I'm going to need to give you stiches and it's going to take some time." Sam said.

"Stiches? Just use the dermal regenerator, it takes like five seconds." Kirk said.

"Sam, they have WAY advanced technology. You'll need a better excuse to protect Kirk." AL said.

Sam reluctantly fixed the captain up quickly but had another idea in mind.

"Captain, do you mind if I post a nurse to you for about three hours? You have a concussion and I want to make sure your fine." Sam asked.

"Whatever, as long as they're not in my way." Kirk sighed.

After the captain left, AL walked over to him.

"Smart plan Sam, but Ziggy says that there's still a 67% chance that Kirk dies." AL said.

"Does Ziggy know where?" Sam asked.

"Most likely in a lift going to the bridge; however, it could also happen on the bridge." AL said.

Sam walked over to a security officer.

"Can you guys conduct a sweep of all the service hatches and lifts near the bridge?" He asked.

The security member was puzzled for a second but then said "Sure doctor, is there a threat though?"

"Possibly, I just want to make sure the captain is safe." Sam said.

ABOUT 2 HOURS LATER:

Sam had been treating the injured for about two hours when he decided to take a break and go to see the captain personally. He left the medical bay and got in the lift to the bridge. On the way up Sam realized something. The security guard he had talked to was wearing his pin on the opposite side of his shirt than was standard. In addition, the ship had just been attacked and he didn't seem on edge even a little.

"AL" Sam asked.

The hologram appeared. "What is it?"

"Who was that security guard that I talked to?" Sam asked.

The hologram looked at his time pad and pressed a few buttons. He then looked up with a shocked expression on his face and said, "His name was crewman Jarred Logan, and he was stationed on a deck that completely decompressed during the Klingon attack." AL said.

"Oh boy!" Sam said before he reached the bridge.

When the door opened he saw the security officer raising his phasor pistol to fire on Kirk. Sam ran and tackled the traitor who in turn tried to fight him.

Sam only needed to contain the man for a second or two before a Vulcan and two other humans where on him.

"Bones, the hell is going on?" Kirk asked.

"Captain, crewman Jarred was on a deck that decompressed during the attack or at least that's where his post was. Obviously he was trying to kill you so my conclusion is that he's working for the Klingons." Sam said.

"Spock, take him to the brig and interrogate him!" Kirk said.

The Vulcan nodded and used his superior strength to hall the man off. Just before the door to the lift closed though, the traitor said, "Bravo doctor Becket! You may have won the battle, but the war for time has only begun!"

"What was that about?" AL asked.

"I don't know, but he knew who I was." Sam said.

"That's bad news, but hey you saved Kirk." AL said.

"What happens to the Enterprise?" Sam asked.

"Well according to Ziggy, they make it back to Earth and Kirk eventually makes peace with the Klingons. And Doctor Bones receives the equivalent of the medal of honor for protecting him." AL said.

Sam nodded as he felt the Quantum energy surge over him.

LEAP

Sam was sitting in a classroom at a desk. He was wearing an orange polo shirt and had blue jeans on. The teacher was going over some very low level multiplication and division. She had put ten problems on the board, all of which Sam instantly solved in his head. Suddenly Sam felt someone tap his shoulder. "Hey Lincoln, I overheard Ronnie Anne talking about pranking you at lunch again. What should we do?" An eleven-year-old with glasses and an afro asked.

"Oh boy." Sam said under his breath.

(Just as a side note, I chose Star Trek and the Loud House as the first few chapters/episodes but I'm open to suggestions. IE: Hey I'd like to see Sam Leap into Godzilla or Darth Vader. Things Like that.)
