Was that last chapter too vague? Apologies. Maybe this'll clear some things up

I do not own Doctor Who, Ben 10, or Animorphs

My name is Jake. I can't tell you my last name, or where I live. We can't trust anyone, not even our own families. Five others and I have the ability to morph into any animal we acquire the DNA from. We've faced evil aliens, masters of dimension manipulating, and even went back in time when dinosaurs roamed…but really, nothing prepared us for this...

Through all of the commotion, the bright green flash of Ben's Ultimatrix got whoever those attackers were to freeze.

"Uh…wasn't he a human just a second ago?" A dark-haired boy on Ben's left asked. "Or am I seeing things?"

"Ugh! It reeks!" A tall, blonde girl gasped, covering her mouth and nose like an impromptu gas mask.

"I don't smell THAT bad!" Ben, now Swampfire, protested from his flat-on-his-back position on the rough, wooden floor of the…barn? He would've confronted that girl if it hadn't been for the freaky bird of prey giving him a death glare, silently insisting on digging its talons into his chest.

"Ben!" Julie cried out. The being holding her prisoner was a being that definitely didn't belong in a barn. It looked like some blue-furred centaur, with hardly any facial features, and two extra eyes sitting on stalks that twitched and looked around. And a deadly looking tail, similar to that of a scorpion's, aimed right at Julie's throat.

"Hey! You let her go! …whatever you are…"

You know exactly what I am, Yeerk.

Ben blinked. This guy had telekinesis? "…Actually, I really don't." He said, shooing the hawk away and getting up. "Now, would someone tell me what's going on?" He demanded, igniting one hand to prove his point.

"Ax? Any chance that's he's Visser Three?" Said the other boy. He seemed like the leader of the group. Less snippy than the other one.

The alien, who was apparently the "Ax" he referred to, turned to this boy, but Ben couldn't hear anything from him. Julie tried her best to keep calm, staring at the blade still level at her throat.

"What's a visser?" Swampfire asked, very confused. "Whatever it is, I'm pretty sure I'm not a visser. Now let her go!"

"I think he's telling the truth…." Another female voice piped up. A dark-skinned girl in stained work overalls watched the whole ordeal from over a stall door.

"I don't know, Cassie." The blonde girl said. "Visser almost fooled Tobias into thinking he was his long-lost cousin, you know."

"Who's Tobias?" Swampfire asked. "Okay, look, you want me to prove myself?" He smacked the Ultimatrix symbol on his chest, reverting to his human form. "See? I'm actually human!"

"Ax, I don't think he's Visser Three, but how can he morph like that?" the brunette asked.

"Oh, that? I transform with this thing!" Ben said, presenting his left wrist. Normally he wouldn't tell his secret to just anyone, but these other kids were calling him weird names and had an alien holding his girlfriend hostage. What could possibly go wrong? "It's called an Ultimatrix, okay? I use it to turn into other aliens."

Ax neared his blade towards Julie's neck, but was distracted by a mechanical growling coming from her backpack. A blob of black and glowing green circuitry poked it's "head" out and…barked? Ax let go of Julie, not taking his main eyes off of the Mechomorph known to its owners as Ship. He trotted towards Ben. Ben froze, unsettled by the two pairs of eyes staring at him and then down at the Ultimatrix. He seized the Ultimatrix, examining it.

...This is not Andalite technology.

"Andalite? Don't you mean Anodite? Er, nevermind. Listen, you probably don't believe me, but we were sent here! We're not 'vissers' or Andalites or Yeerks, okay?"

Ax stared. The work of Ellimists? Who sent you?

"What's an Ellimist?"

Ax gave up, and walked off. Prince Jake, I believe he is telling the truth, but I still have my suspicions…

Jake stepped up. "Sorry about that, he has a personal beef with Yeerks."

"Uhh, sure." Ben said, being joined by Julie. "What's the big deal?"

"Okay, there's only two kinds of people out there right now." The other unnamed boy said. "The completely oblivious people who don't know that there's aliens out there beyond X-Files, and those completely on the Yeerk's side. I bet this guy's a Controller!"

"You're not making any sense!" Julie exclaimed. "If anyone here is a threat, it's you! Just…let us go!"

Ben thought it over for a long moment, while the other kids and the alien (and for whatever reason, that darn hawk staring at them in the rafters) bickered about what to do. The doors on the barn were shut and locked.

"I've got an idea." He told Julie quietly. "What if I explained myself? And somehow proved that I wasn't that…whatever it is you called me."

The four kids and the alien exchanged glances. Jake sighed. "Fine…but you'd better not be pulling some trick on us!"

A cat pawed at a stained food wrapper dangling from a trash can in an empty alley. It tore away from the bin and floated down. Before the cat could sniff out any remaining meat left behind, a loud whirring noise startled it, making it flee from the alleyway.

A translucent blue form appeared from nowhere, gradually forming an old British police box. The lantern sitting atop the roof continued to flare with every whir as the TARDIS materialized in place, finally dulling. The door with a police crest on it creaked open.

"Ah! Lovely! The nineties!" The Doctor said, casually strolling out in his usual brown suit and coat and some sunglasses. "Now, what's going on?" He asked himself, taking his Sonic screwdriver. With a push of a button, the little device buzzed loudly as he waved it around him. The sound stopped. Nothing. Nothing yet, at least.

"Do I look the part, Doctor?" Donna called out. As usual, she had raided the TARDIS's closet for proper nineties attire: denim, plaid flannel, scrunchies, the works.

"Very much so, but come on! Potential danger around!" He said, walking off, waving his sonic screwdriver around.

The town they had landed in was lively, but not busy. Men and women returning home from work, mothers pushing children in strollers, teens listening to music over boom boxes or walkmans. It was all rather picturesque, nothing at all out of the ordinary.

"So…What danger are we facing, exactly? Aside from the trends of the time." Donna said jokingly.

"No idea…" The Doctor replied honestly. He approached a man watering a flower bed. "Hello! John Smith, health department. This is my assistant, Miss Noble." He stated, flashing his psychic paper to the man. To the average eye, the paper would have been blank. Blank until persuaded that the wielder was indeed who they said they were, with their "credentials" printed out on the psychic paper.

The man, of medium height and a receding hairline, frowned at the odd man and his companion. "Yeah, what?"

"Ah, yes, I'd like to know, are their any major events happening around? Any strange occurrences lately?" The Doctor said, anxious for any news.

The man stared at them, but then responded. "Not that we know of, sir."

"Oh, what a shame. Thank you anyway." The timelord said, turning on heel to move on.

The workman then reached out and grabbed the Doctor's shoulder. "But, I think you'd be interested in this, Mr. Health Department." He said, tugging a folded piece of paper from the pocket of his overalls and handed it to them. On it was a picture of a happy family partaking in a picnic. "It's for the Sharing. If you haven't come to one, I'm sure you'd love it." He insisted.

"Oh yes! That Sharing! The Sharing in which…umm…you share…stuff. Right! I'll be there, thank you for your time!" the Doctor said, dashing away, leaving Donna to scramble after him. "Doctor!"

The workman waited until they were far away. He dropped the hose in the flowerbed, uncaring if it drenched the plants, and made his way to a phone booth.

He had an important call to make.

"…And that's how we got here!" Ben finished, exhaling in exasperation. For the past forty-five minutes or so, he had explained to them how he got the Omnitrix, a few of the villains he had fought, how he won against the Highbreeds and DNAliens invading Earth, and how he now had the Ultimatrix.

Needless to say, the four teens and their alien friend were speechless.

Jake was still suspicious, but they've experienced weirder situations. Sure, maybe Visser WAS trying to trick them again, but why bring in another Controller with him? To back up his story? No, too complicated.

"Is that enough proof?" Ben asked.

"So, what, this Paradox guy sent you back in time to help us or something? Sounds like you had your hands full as it was in the future." Cassie said, who appeared to be fascinated by Ben's stories of more aliens living among humans in the future.

"I guess…" Ben said.

"And we're stuck here until Paradox decides to bring us back." Julie said, watching Ship snooze at her feet.

"So, what's the verdict?" The blonde girl, found out to be named Rachel, asked Jake.

All eyes turned to the brunette. It didn't take him long to come up with a decision. "Well, if what you say is true…then maybe you can help us."

"Um…"

"But it's going to be different than those…Hybrids?"

"Highbreed."

"Right. And if you can shape shift, that makes it even better."

Ben exchanged a concerned glance with Julie, then back to the Jake. "Okay, what do I have to do exactly?"
