Orson?

Not Orson.

'Nanu nanu' is something the alien says.

I think I should point out that this password was a reaction to Huey's last one, and has a close connection with it. Some of these clues will not make sense at first ... or, more to the point, the answers won't. Just try to guess the easier ones first, which I would say are 1, 5, 7 and 11. 3 too, if you can see where I'm coming from with that one. Also 6, which is really just a straight clue.

1. The Spanish alien is in turmoil for him.
2. Impolite? It's the opposite! A way of walking, a pronoun ... all mingled!
3. Rocky?
4. Mess it up, but for something warm?
5. Huge drawback to him, but it sure turns out OK!
6. 'Tis rare in Mordor.
7. Behold ... seize ... spin ... it's there!
8. Batman has one!
9. Sounds like a pub, or pub's speciality - this trifle of Sauron's, according to Galdor.
10. One vowel-shift away from a palindrome! See it. Wear it!
11. Sounds like a disrespectful name for the Professor in a particularly tart mood.

Ah, so 1 is Melkor (MORK+EL)

And we're off!
 

MELKOR: The Spanish alien is in turmoil for him.
2. Impolite? It's the opposite! A way of walking, a pronoun ... all mingled!

P.S. Who is Orson?

The character from the same franchise, and Mork's superior officer.

For 7, synonyms of 'seize' is grab, so grab+lo.

Oh ... the one he reported to at regular intervals?

Have you seen any Mork and Mindy? I don't think I've watched it since it first aired.

Yes, that's promising.

Nope. I prefer other cartoony shows, such as Wander Over Yonder and Steven Universe.

Is the theme 'evil names'?

No.

7. Bauglir?

No. You had the elements before.

How stupid I was. I didn't see it. 7 is Balrog, and I've already said why.

5. One ring?
6. Sunlight?

No, but 6 is close.

6. Light in general?

Drawback=failure?

No. What other thing would Sam ask Galadriel for, if he could?

10. Narya, Nenya, Vilya?

Find a synonym.

Gardens?

In Mordor?

5. Snaga?

Correct synonym, but you need another synonym too.

Weapons? Knives? Elvish daggers?

5. Giant snag

Look at the Mordor chapters again.

Which ones? The ones where they journey there, or the ones where they're already there?

Already there.

Can't find it

Water?

Yes. Initially I prefixed it with 'And all the boards did shrink.'

2. Impolite=Unrude?
3. Rocky = Lithic?

Leave clue 2 for now.

3. Think of a film.

Rocky Balboa?


Bilbo?

Right film.

What could Rocky be described as, which could be used as a character title in one of Tolkien's works, too?

Strong?

Hint: as a very famous title of someone. In a very famous Tolkien book.
