Equestria and the Kingdom of science

Samantha hurried to finish gelling her hair into Senku's signature style. Something that had taken her at least an hour to get right, before heading out of the hotel and down to the convention.

"Okay now that my hair is set, all I have left is to get the arm wraps to finish my costume for post-hibernation Senku." She muttered in the elevator. "I'm glad Dad was able to spare the deer hide to help me get the rest of the outfit together but those arm wraps are ridiculously hard to find since they aren't deer pelt and it's an unknown fabric. Hopefully, I'll find something to fix that later."

Samantha exited the elevator to the main hall of the hotel where the convention was being held. Looking around she noticed that not many vendors were active due to the still ongoing pandemic, but she noticed one booth in particular that surprised the hell out of her. It was the smithy from the kingdom of science run by the old man that Senku had roped into working for him in the anime. Deciding to visit the vendor in character she walked over and smiled an evil smile.

"Old man, I'm 10 billion percent sure you have my arm wraps where did you store them?" She asked the vendor.

"Chief Senku I have no idea where your arm wraps are but our friend Chrome might." He replied. "Get out here girl! The chief needs help!"

Another girl in a gender-bent Chrome outfit stepped out of the back of the booth. "Alright, I'm coming!" She shouted back. "Hey Senku whatcha need?"

"I seem to have misplaced my arm wraps. Did I leave them in the lab again?" Sam asked, still in character. "Also do you have anything else in there that might spark my interest?"

"Yeah to both of those." The Chrome cosplayer replied. "Found your arm wraps and these neat plastic and metal things in the lab. The only thing that bothers me is the labels on them. They read 20$ on all three."

"It's a form of currency exchange labeled on their Chrome. I'll take care of it." Sam said as she began to take out 60$ in twenties, passing the bills to the old man. "That should be enough."

"Yep, that's right pass them over to the Chief girl." The old man said.

"K," the young girl said as she handed Sam the arm wraps of an off-brand Xbox controller and a plushie of an alicorn Senku wearing a Medusa device on a necklace. The plushie emitted a green light from the horn before Sam blacked out.

When she came to Sam noticed she couldn't move and she heard a number counting up in her head. "This ain't good if my mind is counting like this then I must now be stuck as Senku on Equus meaning those two were merchants! Still given all I know about the series it's not the worst fate in the world I can still break out as long as I'm in contact with nitric acid." She thought as the counting continued. "Depending on where I am in the timeline and they even have some fellow hibernation mates in Discord or even the trio of doom." With those thoughts out of the way Samantha now Senku resolved to wait out at minimum the 3000 years, it took Senku to break out in the canon. "Ok, all I have to do now is wait…"
