The Doctor arrives at Babylon 5(DrWho/Babylon 5)

[FaxModem1]

The year is 2257, the episode is "Signs and Portents".

When Mr. Morden arrives, so does the Doctor in his TARDIS in Down Below. What happens?

Does he prevent the Shadow War? Does he let it pass?

As for what Doctor, I pick Ten, since he's the second most recent and he's had the most mileage of the recent ones.

[Stark]

What's the hook? What, if anything, serves to draw him into events? Ten especially was inconsistent and easily swayed, so what happens immediately after his arrival will strongly colour his attitudes.

[PREDATOR490]

Doctor looks around, does some exploration and leaves.

In the off-chance the Doctor bumps into Morden the chances of anything happening are remote. Morden has no reason to interact with the Doctor and wont give a shit about him. If the Doctor pushes the issue or reveals the Shadow's then the Doctor will start the war early.
Is the Doctor going to sit around in the B5 universe for the better part of 1 - 3 years fighting a war ?
No, it becomes highly likely he will bail out at the earliest opportunity and claim it's a fixed event / the way things are meant to be.

At best the Doctor might stick around to help initially but going to war with the Shadow's at this point is suicide since noone is ready. The Whitestar Fleet is still under production, Sheridan aint going to be able to push Kosh to intervene and with events fucked up like that the Time-Loop of War Without End gets broken.

[Thanas]

The doctor can quite easily destroy every opponent of the B5 verse, if he wishes so.

As what draws him in I think Rose might easily stumble upon things. Lando will try to get into her pants, the mimbari will go wild about the doctors telepathic abilities (as will the Psi Corps) etc. Really, the best bet is Talia trying to read his mind.

[PREDATOR490]

Morden has no reason to interact with Rose and there is no reason to believe Morden is going to approach the Doctor or Rose when they are nobodies.
If the Doctor or Rose start messing things up to get noticed by B5 personnel then it becomes more likely Morden will eventually catch wind of the Doctor's power and have him killed or manipulate events to get the Doctor to go away.

Only two people know the Shadows are even around at this point and they do not want the Shadows to know this. The Doctor's Telepathy is no where equal to that of the B5 verse so I dont see how anyone will really care about the Doctor when his Telepathy requires physical contact.
Can he block B5 Telepaths ? - No idea,
Would they try ?
Humans are unlikely since its against the rules and
Aliens - Possibly

If the Doctor reveals the Shadow connection to Morden then the Shadows launch their assualt early. Is the Doctor going to fight the entire might of the Shadow on his own ?
Sure, he COULD commit genocide and wipe them out but the Doctor is far too squemish.

[Revy]

Well if it was Eleven rather than Ten I doubt the Doctor would have any problems. He would just tell the Shadows to look into his mind, give them a big impressive speech about how much made of win he is, then suggest they run away while they still can.

It requires no contact, for otherwise the Tardis would not be able to have him communicate in English or translate stuff between aliens. Sure, very delicate operations require contact, but brute force might be different.

That depends. He did wipe out the daleks and other threats. It really depends on how much they decide to push him.

Unless you can bring up an example of the Doctor using Telepathy as a weapon or in an aggressive manner there is no indication the Doctor can do this.
Regardless, Telepaths are well known in the B5 verse and by their standards the Doctor wouldnt even rate being a Commercial Telepath. Since he isnt human the Psi-Cops cant pull him in and in the off-chance they decide to go after the Doctor they are trained to resist Telepathic Attacks.

The connection between him and the TARDIS remains largely unknown and such a connection could be detectable by Telepaths of the B5 verse. Regardless, the chances of the Doctor being a mind shredder seems extremely unlikely. Assuming he would dare use his ability like that.
Could the Doctor resist a Telepathic Assualt like that ?
If he cant then Bester appears, scans the them and mind rapes him and Rose to the point their brains leak through their ears.

Can the Doctor project a Telepathic signal capable of disrupting the Shadow Vessels ?
I find this exceedingly unlikely but if it can be done then the Doctor could help a little.
Although the Doctor's squemish nature about killing or being involved in such makes me think he would refuse to 'deadlock' a Shadow vessel while it gets gunned down.

I dont see how the Doctor is going to be able to wipe the Shadows out and if he screws up events the Time-Loop gets broken and the Shadows get an instant win because Babylon 4 will not appear during the last Shadow War to help them win. Sinclair wont become Valen and the Minbari get royally screwed as a race.

I still find it exceedingly likely the Doctor will either leave because he sees events as 'Fixed' or decides 'things are the way they are meant to be'.
This assumes the TARDIS is even remotely functional since jumping realities is no longer possible. Doing so resulted in the TARDIS almost dying.

You probably mean Londo, since Lando is doing business in another universe, and it's Minbari...

As for a hook, are we certain he can't see the Shadows through their cloak? Might make him at least slightly interested to stay...

There was no indication how the Shadows actually cloak but assuming the Doctor has a reaction to them. He has nowhere to turn to get information except two people. Asking questions about the Shadows either leads to Morden and Co. murdering the Doctor or exposes the Shadows and kick starts the war off years early.
The Whitestar fleet is still under production and without them the Shadows possess a hefty technological superiority
The Minbari have internal issues and the disruption of events could even take them out of the war at this point
The Narns and Centari are too busy trying to kill each other with Londo about to sell out to Morden
Earth Gov is being subverted by Morden with the assassination of the President coming and the increasing Anti-Alien sentiment being spurred on
Vorlons wont intefere and without someone to push Kosh they will remain so. In the off chance the Doctor pushes Kosh it results in both sides going crazy nuking entire planets.

Likely outcomes:
Doctor reacts to the Shadows VISABLY - They kill him or attempt to - War starts
Doctor sees the Shadows and starts asking questions - Gets little answers - Kosh and Delann tell him to shut the fuck up or the Shadows attempt to kill him - War starts
Doctor dosent see fuck all, wanders around until he gets bored and leaves - Doctor brings too much attention to himself and gets targeted by interested parties - Shadows take a shot at the TARDIS - War starts

I think that the second one is the most likely.

I can already see him wandering around the station, asking strangers how many people they see in the room, while telling Rose how humans are so quick at assuming that people = humans and don't see past their own nose. Maybe try his magical paper with Morden to verify what he sees.

At some point, he will notice that the only ones to consciously avoid getting near Morden are Kosh and Delenn. From there it depends if he is going to look under Kosh's suit and talk to him *ahem* eye to eye about the upcoming war and how it will fuck up everything.Basically it would be Sheridan's talk but with the Doctor's verve.

From there, well it depends on whoever write the story.

Was it me I'd say that Morden kidnap's Rose to keep the Doctor in check. This would lead him to get the Tardis to Za'adum and make a little speech about how powerful it is. And that he may put that power to good us unless Rose is returned to him.

[PREDATOR490]

It is extremely unlikely the Doctor would figure out Delann and Kosh know about Morden simply through observation. Morden tries to avoid Kosh and their eventual encounter is less than friendly. If I recall correctly Kosh reports damage from his suit in this episode which suggests a fight occured. If the Doctor bumps in on that, I find it likely he is going to get killed or cause the war simply by being in the wrong place at the wrong time.

Otherwise, the Doctor sees the Shadows, walks around asking questions aimlessly or tries to bring it up to the B5 personnel. Sinclair / Garibaldi might take him seriously but they arent going to have a clue what he is talking about and investigations into Morden will just reveal what Sheridan found. I doubt either will push as hard as Sheridan did and it's likely Delenn will tell Sinclair to stop. If the Doctor or B5 personnel take a pot shot at the Shadows then the war starts.

As for Rose, I would find it more likely the Shadows will kill her and make it look like someone else did it. Which is exactly what they did to Londo.
Watch as the Doctor takes out his rage on Earth, Narn or the Centari and weakens the races enough for the Shadows to mop up unchallenged.

Without a character shield or writers fiat making him always right - The Doctor's actions at this point are exceedingly likely to get him, Rose and alot of people killed in his erratic wandering.

[Thanas]

Doubtful. Much of his stuff is an act or him just being a dick. And far more dangerous people than the Shadows have tried to kill him and did not succeed.

[mr friendly guy]

Unless you can bring up an example of the Doctor using Telepathy as a weapon or in an aggressive manner there is no indication the Doctor can do this.

Er "King's demons", "The Brain of Morbius," "The abdominal snowman" and "Web of Fear" (granted those last two serials have lost episodes, so the telepathic battle might not longer be available, but the novelisation clearly show the Doctor using telepathy against the "Great Intelligence").

Also examples of defensive telepathy include "The Five Doctors."

Can the Doctor project a Telepathic signal capable of disrupting the Shadow Vessels ?

Most probably not, and its very difficult to assess, since we don't really have a great quantity measure of telepathy. However why doesn't he just, I don't know tractor beams one of them and dumps them at the other end of the universe. It tractor beamed Earth in Journey's End and a neutron star in Creature from the pit, I doubt a shadow vessel has anywhere as much mass as those objects.

I find this exceedingly unlikely but if it can be done then the Doctor could help a little.

Tractor beam, dump ship at other end of universe. No loss of life and hyperspace travel will take.. how long to get back to the Milky Way galaxy. Oh, and if you want evidence that the TARDIS can reach the "edge" of the universe look up the Tom Baker classic "Planet of Evil."

I dont see how the Doctor is going to be able to wipe the Shadows out and if he screws up events the Time-Loop gets broken and the Shadows get an instant win because Babylon 4 will not appear during the last Shadow War to help them win. Sinclair wont become Valen and the Minbari get royally screwed as a race.

I think its fair when we conjure up a vs scenario, that "events going to AUTOMATICALLY happen same as before" no longer applies.

This assumes the TARDIS is even remotely functional since jumping realities is no longer possible. Doing so resulted in the TARDIS almost dying.

Well that would depend on the plot device that allowed him to enter B5 space, which is not defined in the OP. I mean if we do a SW vs ST scenario, no one is going to say well SW ships can't transverse universes anyway, so it will never happen. The author will come up with some technobabble plot device like a wormhole or "spatial anomaly of the week". If you want to see what happens without the Doctor being handicapped you will have a similar plot device.

[mr friendly guy]

I can imagine various scenarios where the Doctor just wrecks havoc because of his awesome character shields and plot devices. Can you imagine

1. The Doctor steps into the vortex via the heart of the TARDIS and destroys the Shadow fleet. Oops, RTD already did that crap. Just for the record its not the only time someone stepped into the vortex and gained powers. Apparently in the comics the Doctor did that and managed to make an immortal Eternal mortal.

2. The Doctor convinces people he is Jesus, and builds a satellite where he taps into the hopes of the allied species and wanks destroys a few Shadow ships. Oh wait, RTD did that crap as well.

3. The Doctor drops a mundane object like a spoon onto a ship and then the ship starts disentegrating due to wank microscopic lifeform on the spoon - "Infinite quest."

4. He tricks a fleet into following him after giving them some tech, which is really a trap, because due to technobabble and more technobabble he time loops them. The TARDIS then proceeds to break out of the time loop - Claws of Axos

5. Dumps ships into a black hole via use of a tractor beam - I believed he dumped one of the family of blood in a blackhole.

6. Or how about I take some liberties and have him build a telepathic magnifying device or modify the main deflector to emit quantum particles telepathic circuits to boost Lyta's telepathy. I say liberty because I don't recall him building one before, but TL clearly have the ability to create such tech "The Five Doctors", and he understands a bit about the principle - "Planet of the spiders" and of course the aforementioned using the telepathic tech from the Master's archangel satellite network, not to mention the TARDIS telepathic circuits which boost telepathic communication (see The Time Lords contact him via the circuits in Hand of Fear).

This guy is a walking plot device. Depending if he is in "the mood" its conceivable he could defeat the Shadows if he plays his cards right.

Oh, and another thing. The Doctor also demonstrates telekinesis, albeit on a small scale - see "War Games". Just for interest there are also stronger Time Lord telepaths out there. In War Games they simply forced the War Lord to talk at his trial in a matter of seconds via a telepathic attack which made him feel intense pain, and Selyavin whose telepathy supposedly could affect an entire world IIRC (from "Shada").

[Themightytom]

I could believe the doctor can see the shadows, he seemes to have SuperSmell and Super Taste to the point where he can detect left over teleport ions and what not. He would notice an invisible object taking up space and making little buzzing noises.

Not to mention at least some level of telepathy.

He might be helpful in getting Kosh to act sooner, or more directly, whether that is good or bad i am not so sure. I'd ahve him talk to Kosh, get his side but decide "you know what this doesn't add up. I'm going to Zahadum to find out the other side."

Cue the Doctor coincidently bumping into lorien, and brokering a truce between the Shadows and the Vorlons.

I suspect his role as "Time Lord" might appeal to the Vorlon as lords of order, while his innate nature would appeal to the Shadows as agents of Chaos.

I ALSO wouldn't be surprised if he was able to somehow sonic screwdriver the shadows, make the vorlon encounter suits lock up and spark to enable a quick get away, or communciate on some sympathetic level with a Vorlon ship the way he does his TARDIS.

personally though i'd rather see him in a story involving Mollari and his keeper.

[Patrick Degan]

I've often thought of a simple, quiet one-off scene in which the 7th Doctor is passing through the station, during which he encounters Mr. Morden and asks him what he wants. Just to rattle him and his handlers, who start nervously chattering and whispering to themselves about the "Bringer of Light".
