Author's note:

Hey everyone! This is my first trollhunters fic because I'm new to the fandom but I became inspired because I was blown away by the story and I love the characters so much.

This will be an Amnesia!Jim one-shot. I got the idea when in season 2 episode 11 - Unbecoming. Recap of the episode: Jim was given a second chance to choose his destiny by a previous trollhunter resulting to everyone forgetting that he was the trollhunter because the amulet never chose him. But what if it was the other way around? And Jim was the only one that forgot all of his adventures.

Side note: Jim is human here and has been the Trollhunter for 4 years. He, Toby, and Claire are around 19 years old.

(DISCLAIMER: I do not own any of the characters)

"Dr. L come quick! He moved! I think he's waking up."

Jim hissed at the sharp pain splitting through his skull. It felt like there were talons clawing at the back of his head, making him wince. He heard his friend Toby calling for his mom but he wasn't sure if it was him. Was it just him or did Toby's voice suddenly became deeper?

"Hang in there, Jimbo. You're mom's coming."

"Oh, so it is Toby." Jim thought, knowing that nobody else would call him 'Jimbo.' He did not dare open his eyes to check though, fearing the pain would get much worse. Slowly, he reached for his head, feeling bandage wrapped around his forehead and the back of his skull, as he tried to massage the agony away.

He heard rushed footsteps going up the stairs and into his room. Then he felt his mom's presence beside him. "Jim? Honey? Are you okay? How do you feel?"

Jim opened his eyes slightly to look at her, and almost immediately dark and white spots danced in his line of sight. The world spun and he felt like puking as he moaned and forced his eyelids to shut.

"Mom?" Jim croaked. Even his voice sounded weird but that was probably due to the ringing in his ears. He opened his eyes again, his room was still spinning but he could still see his mom, and the worry written all over her face. "What happened?"

"Oh boy! You should have seen yourself fly, Jimbo! You weren't wearing your helmet when that catapult floor launched you to 20 feet in the air. You slammed into Unkar's statue hard but it's a good thing AAARRRGGHH! was there to catch you." Came from the boy standing next to his mom, whom he assumed was Toby but also didn't look like his friend from yesterday.

Since when did Toby get taller? And buff? He looked like a mini version of Coach Lawrence. His shoulders were broad. His hairstyle was different, combed only to one side now. He wasn't wearing his normal red sweater vest anymore, only a red hoodie and brown pants. His face was more chiseled now than chubby. And he didn't have braces anymore.

"Tobes?" Jim squinted to see if the guy, was really his best friend. "Is that you?"

"Yeah dude, who else would it be?" Toby said with a concerned look.

He wanted to ask more questions but he remembered Toby's previous explanation. "Wait... wait... wait, back up a second. Accident-? What do you mean fly? And what's an ARRRGGGHH?" Everything that he said made zero sense.

His mom and Toby exchanged nervous glances. Barbara placed a gentle hand on his hair. "Jim, what was the last thing you remembered?"

Grunting, he tried to sit up on his elbows, trying to think back the last thing he remembered. And judging by his mom's face and Toby's sudden growth spurt , he must have forgotten a lot.

"Uhhh, I was-" Jim looked at Toby, "We were playing 'Go-Go-Sushi' last night Tobes. And you did your happy dance after getting another high score."

Toby's face fell, "Uh-oh."

Even more confused than ever Jim sat up all the way, "What? What's going on? And you would you please explain to me, how you suddenly look like that, Toby." Gesturing to his bulky built and older features.

Barbara sensed his confusion and feared the worse, "Honey... how old are you?"

Jim looked at his mom with even more bafflement than he did with his best friend. "What do you mean? I'm... I'm fifteen, mom. My birthday is in a couple of weeks."

Barbara gasped. "Double uh-oh," Toby said.

"What? Why? What's happening? You guys are acting weird," Jim is now even more frustrated with the confusion rather than the pain in his head.

Toby walked up to the side of his bed, and hesitantly placed a hand on his shoulder, "Jimbo, that night that you remember..." he paused as if afraid of what he''ll say next, "...that was four years ago."

Jim's eyes widened, "What?! That's impossible! I slept that long?" He put a hand on his chest, he felt his heart racing.

His mom tried to calm him, "Honey, you didn't sleep that long. You had an accident. Maybe the impact of your head collision was pretty hard so it might have given you memory loss."

"Four years," Jim gasped and ran a hand through his hair. He forgot four years of his life. He wondered if he did anything extraordinary in those years.

"Oh no," Barbara placed a hand over her mouth as if she remembered something.

"What is it Dr. L?" Toby asked before Jim can.

"I was on the phone... with Blinky. Just before I hung up you yelled that Jim was awake. He probably heard that and he's with ARRGGGHH! I think they're on their way right now and they probably told Claire too."

"C-Claire Nunez?!" The image of Jim's long-time crush seeing him in his current state had him blushing. He looked down, now only noticing that he wasn't wearing a shirt, making his face even redder. Then his brain caught on another name that his mother mentioned. "Blinky?"

Toby laughed timidly, "Yeah, Blinky. You know... the one that helped you build your Vespa. Your mentor-slash-trainer, father figure-slash-troll dad."

"T-t-troll?" Jim stammered. Unsure if he heard his friend right. "What are you talking about? And why were you on the phone with Claire, Mom? If she saw me like this... oh man." Jim buried his face in his hands in embarrassment.

"Well we kind of figured you'd want to see your girlfriend first when you wake up," Toby answered for Barbara.

"Girlfriend?! Claire is my-"

"Yes, she is. She was here earlier, watching over you but she had to leave to do some errands for Blinky in Trollmarket." Barbara gently explains to her son.

Jim was about to ask more questions when he heard a sound from downstairs. His eyes widened when it sounded like something big and heavy busted through the kitchen door. Then lumbering footsteps approached from the stairs, shaking the whole house. "What is going on?!" Jim exclaimed in fear.

"Oh that's just..." Toby tried to explain but didn't finish when the door to his room slammed open, making Jim jump. "Ahhhhh!" He yelled in fear. A sudden blur of green and gray clouded his vision. Huge hands lifted Jim and hugged him to a huge rock like surface.

"Monster," Jim managed to squeak out as the creature continued to crush the life out of him.

"Not monster, troll. It's me, AAARRRGGHH!" The creature bellowed in a booming deep voice and it scared Jim even more when he learned it could talk.

Another voice spoke from behind them, this time more well-mannered and sophisticated, "Now, now, AAARRRGGHH! Kindly let go of Master Jim before you kill the poor soul."

"Yeah, wingman. Ease up on the troll-hug. He's turning purple." Jim heard Toby say. The big troll finally let Jim go.

Jim landed on his bed and screamed once again when he finally saw the trolls in full view. The one that was hugging him was ginormous. He was surprised that the thing can even fit in his small room. It had big green eyes, as well as green fur covering the upper part of its body. His big, sharp teeth looked like they were smiling at him. The other one was smaller but still taller than most humans nonetheless. This one was blue and had six eyes and four arms. He looked at him fondly, like a father should to his son.

"Hmmm... not the kind of greeting I was expecting." The blue troll commented.

"He's in shock, Blinky." Barbara said, and Jim wondered why she and Toby were acting so calm around these monsters. "I don't think he knows who you are. He might be missing some memories because of that accident."

"Ah, to be expected." Blinky laughed in relief, "The modifications I did on the Hero's Forge did have some mischievous surprises and he did hit his noggin quite hard on Unkar the Unfortunate's statue after being launched by that catapult."

"It was more of an eject floor really," Toby told Jim. "None of us saw that coming."

"But no matter!" Blinky announced confidently. "I'm sure it will come back to you eventually." He grabbed Jim by the shoulder and sides with his four stony arms, and looked him in the eyes. "Your memories will be restored soon enough, Master Jim."

Jim was still petrified. The six eyes staring into his soul wasn't helping calm his nerves. "I-I... how? What? Who-?" So many questions came to mind and he can barely keep up with what was happening.

Just then a new sound came from downstairs. He already knows from watching too much movies that that sounded like a portal opening. He heard another set of footsteps approach his bedroom, lighter this time. Jim peered to see who it was just to see the most beautiful young woman he has ever seen in his life.

"Claire?" Jim swallowed. He definitely remembered the pretty girl in Mr. Strickler's class yesterday and he was sure that she looked nothing like the gorgeous angel running towards him.

The facial structure was the same except somewhat older looking, like all the childhood had melted away from her features. Her once short hair clipped with colorful barrettes was now a cascading waterfall of raven locks down her back. The blue streak in hair hair was replaced with a white streak. Her outfit was different as well. She no longer wore a purple jacket. Only a tight purple tank top underneath a loose crop top which exposed the skin of her neck and parts of her shoulders. Dark jeans covered her legs. The only thing same was her old black boots.

The trolls stepped aside just as she leaped onto his bed. She crawled to get closer to him and then grabbed Jim's face in her hands. "I've been so worried, you dingus!" She breathed in relief before leaning over and molding her mouth with his, giving the most breathtaking and best (first) kiss of his life.

When she released him, he stared at her for a moment. Almost losing himself in those chocolate brown pools for eyes, before finally managing to find his voice. "This has to be a dream."

Side Note: Just to give you guys an insight if you're all having trouble imagining the characters as grown ups. Jim's look and built is similar to Tadashi Hamada in Big Hero 6 (look it up). For Claire, I saw a lot of great fanart of her on Tumblr so just check out the drawings. Lastly for Toby, I guess he was the most simple of all the three. His body is somewhat close to Coach Lawrence but not as tall or bulky, he still has some baby fats but most of it is gone thanks to training the Hero's Forge and the dieting.

Anyways, I'll leave the rest up to your imagination.

Let me know if you want a part two for this story. I'll be doing other one-shots as well. You guys can also request or give prompts but I won't guarantee if I can post very often (or if it will be any good LOL).

Thanks for reading! Comment your thoughts!
