This is a crossover between Star Trek: Deep Space Nine and Doctor Who. I do not own either of these shows.

In the DS9 timeline this is set between Seasons One and Two. In the Doctor Who timeline this is set between Series Six and Seven.

I am only thirteen and this is my first story on this website, so don't crucify me if my writing is a bit off. I hope you enjoy!

EDIT: Thanks to Evenmoor for pointing out a simple mistake regarding ten bars of gold-pressed latinum, which I have changed to five strips.

Chapter One: The Blue Box

"And he threw me against the wall and just took all my latinum!" a bruised female gambler said to Constable Odo.

"And what species did you say he was?" Odo asked her.

"Bajoran!" she replied.

Odo looked up to the higher levels of Quark's Bar and saw a Bajoran male gloating and showing his friends his latinum. If it was his latinum.

"And… how many strips of gold-pressed latinum did he take?" he asked the gambler.

"Five." Odo looked back up at the Bajoran. He held five strips of gold-pressed latinum. Odo then gestured to two security officers.

"That man up there with the latinum strips," he said to them, pointing at the Bajoran. The two went up the stairs – one grabbed the man by the shoulders while the other confiscated his latinum strips. The man was brought back to Odo and an officer gave the gambler back her gold-pressed latinum.

"Well then," Odo said to the Bajoran, "you and I are going to have a little… talk. Take him to the brig." The officers escorted the man out of the bar while Odo took a seat at the bar. Quark was pouring some drinks when he saw him.

"More complications again?" the Ferengi asked him.

Odo sighed. "I'm tired of these constant… robberies. I don't see why humanoids see the need to steal things they don't require. They should be focussing on what they have, not what they want."

Quark almost seemed offended. "And as Ferengi, we have our desire for profit, so we have every right to focus on it."

Odo was about to respond when his combadge beeped. "Sisko to Odo," came the voice of DS9's commanding officer.

Odo tapped his badge. "Odo here. Go ahead."

"You are needed in Ops immediately."

"I'm on my way." Odo tapped his combadge and stood up. "If you'll excuse me," he said to Quark before heading out of the bar.

Commander Benjamin Sisko watched the screen in Ops, which showed a large image of the Bajoran wormhole. He turned to see Odo emerge from the turbolift.

"What is the problem, Commander?" Odo asked.

"The wormhole, Constable. Something is happening with the wormhole." The two of them watched as a bright light flashed from within the wormhole.

Lieutenant Jadzia Dax was manning a console. "I'm reading strange bursts of an unidentified type of energy emitting from the wormhole that seem to occur every thirty seconds." Immediately after she finished speaking there was another flash from the wormhole. "It… it seems to be getting stronger every minute! Benjamin… this much energy could cause the wormhole to implode!"

There was another flash from the wormhole, but this time it caused the station to vibrate slightly.

Chief O'Brien checked the censors. "Sir, there appears to be a small rectangular object emerging from the wormhole," he said.

Sisko turned his glance back at the screen. Another flash, brighter this time, shook the station more strongly. Suddenly he saw it.

It was tiny at first, but Sisko could make out a strange blue box emerging from the wormhole.

"Magnify," he ordered; the screen zoomed in to the unidentified object. The box looked around two metres tall. It seemed to have two windows on each of its sides, and one side had a pair of doors. Above the doors read the words: POLICE PUBLIC CALL BOX.

"A police box?" O'Brien said, confused. "But they've been non-existent for centuries!"

"Looks like someone's done their homework," Sisko commented.

"I'm also reading massive energy readings coming from the box," Dax said, "but… that's impossible! A box even of that size couldn't hold this amount of energy!"

"Life signs?" Sisko asked her.

Dax paused. "There's so much energy it's dampening the scanners; for all we know there could be someone inside."

"Is it safe to beam aboard?"

"The box seems to be strong enough to contain all the energy, so I'd say it is."

"Lock onto it," Sisko told O'Brien.

"Locked on, sir."

"Prepare to beam aboard."

O'Brien suddenly looked shocked. "Wait… it's dematerialising! I haven't even beamed it aboard, and it's doing it itself!"

Sisko looked back at the screen. Sure enough, the box disappeared from sight.

Suddenly Sisko's combadge beeped. "Kira to Ops."

Sisko slapped his badge. "Sisko here. I see you're back from your mission. What's the problem?"

"What sort of a joke is this?" Kira said in her usual angry tone.

"I'm sorry, I don't quite get you."

"The box! There's a box smack bang in the middle of the Promenade!"

Sisko was surprised. "Is it, by any chance, a blue… police box?"

"Yes. Why?"

Sisko was in disbelief. This is going to be interesting, he thought to himself.

So, that's the end of the first chapter. Tell me if I got a few things wrong. Please review!
