Ben 10: Heroic Pathstrider (HSR Crossover)

Then There was a Big Brown Dinosaur

In a galaxy far, far away, amidst the stars, was a futuristic locomotive-looking train cruising through the space.

It was a peculiar, yet breathtaking sight.

The conductor of the said express, a bunny-looking something wearing red attire, was sweeping the floor with their tiny broom. They glanced at the five other people boarding the train and made a sigh of relief; it brought back memories of the good old days now that this place is livelier ever since the red-haired woman over there, sipping coffee, made the train run again.

Back then when the train crashed, it was only them and that rich woman who singlehandedly fixed the all by herself when she learned the origin of it. Now, four other people joined along the way; with the gray-haired aloof girl being the most recent passenger.

And for some reason, she's intently staring at the trashcan.

"What are you doing, Stelle?" A listless-looking boy with teal eyes, wearing a white overcoat over a black turtleneck shirt, said to the trashcan enthusiast girl.

"Dan Heng, it's telling me something... "A dinosaur swimming in the sea of stars will board the Astral Express." I think it's a prophecy, even." The amber-eyed, gray-haired girl, totally said that with a straight face.

"The spirit of the Trash is strong with this one..." Another female passenger, this one with pink hair and wearing a cute dress, said with a sagely face.

"Not you too March," Dan Heng facepalmed.

"I've read that in an ancient comic book! Thought it was appropriate to use it now." March 7th cheekily responded.

"... I'm surrounded by idiots."

Of course, Dan Heng, you're following the Path of Trailblaze; you ARE bound to meet interesting people in your life.

"Well, no use overthinking it," Dan Heng muttered before asking Stelle once again, "Stelle, did it show you anything? A vision to accompany its prophecy?"

Since Stelle was weird but pretty honest from the get-go, he thought it was okay to go with the flow when dealing with her.

"Yeah," She immediately replied before using body language to further describe what she had just seen, "It was a big, sleeping dinosaur coming towards our way."

The other two were... Let's just say bewildered. No one in their right mind would believe something like that.

"Oh no! I didn't know Stelle was this lonely and now she's starting to come up with imaginary friends!"

March was acting a bit panicky but Dan Heng still retained a calm face - and barely stopped himself from making a long sigh.

"Calm down March. I think it's nothing to worry about, she has a Stellaron inside her so this might be one of the unknown symptoms caused by it."

Hopefully.

"Hehe, what's gotten you guys riled up?"

The previously mentioned rich redhead appeared before the trio. She seemed pretty gentle and elegant, yet there was this hidden aura of confidence oozing from her.

"Hello, Ms. Himeko. It's nothing major to worry about; just that Stelle was... talking to a trashcan and says it showed her a prophecy of some kind. I believe... it's one of the side effects of having a Stellaron inside her."

"That's likely. Stellarons are pretty mysterious and volatile, after all, so it's difficult to study them. Though I would say don't take this seriously; this "vision" of hers seems harmless enough."

"I think we should-!"

[EMERGENCY! EMERGENCY! LARGE SENTIENT LIFEFORM DETECTED!!!]

Just before March could coin her two cents, the conductor's voice rang out in panic due to what came up on their radar. Spoiler alert: they weren't happy with what they'd just seen.
