This is probably the biggest fan fiction task I've pulled off: Writing a three-way crossover...and MAKE IT WORK D:

First things first, yes, this first chapter is a bit crappy. And obviously, I do not own Ben 10, Animorphs, or Doctor Who.

Without further ado, enjoy!

Ah, Mr. Smoothie, the gathering place of the young people of Bellwood. Two of these young people would be a couple, Ben Tennyson and Julie Yamamoto. The former was pridefully describing his final battle against his long-time foe, Vilgax. The latter? Listening with the occasional eye roll. Julie had heard all of Ben's great (and exaggerated) achievements before, but she was supportive of him nonetheless…and rather enjoyed his silly acting.

"And KA-BOOM!" Ben exclaimed, throwing his arms out. "Vilgax and his ship were no more! Thankfully, I managed to get the heck out of there with Jetray!" He plopped back down, taking a sip of his smoothie. "Mm, lamb and sardine flavor! Anyway, pretty cool, huh?"

"For the umpteenth time, yes, Ben." Julie giggled. "I just can't believe that, even after all those times you've defeated Vilgax before, he still comes back!" she added, a genuine tone in her voice. Being the girlfriend of a guy who transformed into aliens was odd enough, but witnessing the things he went through was plain crazy!

But thankfully, today the two were spending the afternoon alone. No aliens, no enemies, no danger. Or so they hoped.

"Yeah," Ben grinned "They never learn. The bigger they are, the harder I kick their sorry butts back into the Null Void! Just because they're big and bad doesn't mean I can't take 'em!"

"Ah, but what if they were bad, but not quite so big?" A familiar voice said. A lot of weird aliens and villains showed up at Mr. Smoothy's, but this was certainly a first.

"Professor Paradox?" Ben exclaimed, shocked to see the time traveler appear at that moment. And normally, that meant something bad has or will happen. "Is something wrong?"

"Well, no, not really. Pleased to see you again, Ms. Yamamoto. Care for a gumball?" The professor kindly added, holding out an old sack filled with his favorite treats.

"What gives? Is a universe collapsing or something?" Ben was eager to know, hungry for a little action.

"Oh no, not at all. I happened to drop in and overhear your conversation. Pray tell, Ben, have you heard of the Yeerk War?" Paradox asked with a solemn expression. He had said those last two words with the utmost bitterness.

"…doesn't ring a bell." Ben admitted. "I think I've heard Grandpa Max say something about it, but I don't know what that is."

"Most likely you lived through it, but were too young to even remember." Paradox stared off into space, recalling this war. "One of the greatest secret wars in history, and it's only a passing memory now."

"Listen, Professor." Ben butted in. "I appreciate the history lesson…kinda…but what does that have to do with anything I said?"

"Well…you have indeed fought many 'big and bad' foes…but never taken on enemies that are much, much harder to fight." Paradox's demeanor changed "I propose a field trip! Wouldn't that be wonderful?"

"A field trip?" Julie didn't like where this was going either.

Before either teen could react, Mr. Smoothy disappeared. Everything was rushing around them, and suddenly, they were surrounded by people. Everything after that was a blur.

"What the?"
"Controllers!"
"Here?"

"Huh? Where…?"
"Get them!"
"TSEEEEER!"

I have the female!
"BEN!"

"JULIE!"

"Whoa!"

The TARDIS lurched suddenly at an angle, nearly throwing the Doctor away from the control panel. "What's this?" He asked himself, checking all the controls. Everything should've been working accordingly! …Then again, when did the TARDIS ever work accordingly?

"What was that?" Donna demanded, her thick red hair bouncing off her shoulders as she bounded up the stairs. "Slam on the brakes why don't you?!"

"Wasn't me!" The Doctor piped up. He leaned over the controls. "What is it?" He said softly, as if talking to a young child instead of a machine. "What's got you worked up?"

"It's not going to talk back, if that's what you're hoping for." Donna retorted. "I suppose we're not going to that Midnight planet you were talking about?"

"Ohh, but this could be much more exciting!" The Doctor said, acting giddy as the TARDIS sped through the time vortex. "Now, what's our destination?" He asked himself, looking up at the randomizing view screen. Letters and numbers jumbled and came to an exact time. The West Coast of America, 1995.

"Ah! Let's see what the 90's has to offer us! Hang on Donna!" The Doctor announced, throwing the switch to put the TARDIS into full gear. "Allons-y!"
