small text translation help needed

[Who Knows]

I would like to see this writed in romanji and other styles.
"The Unknown X" (or if not possible, then only "Unknown")

I tried to translate it with translator, but they give so many different words...

[Sachi]

The Unknown X? If it's a title or name, if would be written in katakana, correct? This is what I would do:

ウンノーンX
unnoon X

Or something similar. I dunno. Just my opinion, really...

[Harisenbon]

Your romaji is a little off. あ would be better What you have is Oohnknown
アンノーン

but I still wouldn't write it like that.

there's a lot of ways to say it, depending on what you're using it for.
I like the novelistic way
知られぬX
If you're talking about a person
無名のX
A country or something
未知のX

[Who Knows]

Forget it... Next question

How do I write "Unknown Power"

[tkbits]

What kind of power?

Capabilities? as in This person has an unknown Power.
Deities? as in This world was created by an unknown Power.
"Energy"? as in This machine uses an unknown amount of power or We don't know what it's powered by.
etc.

[Harisenbon]

Well, you now know how to say unknown X
知られぬX.

power is 力 (ちから）.
If you were to say unknown power, how would you put it together in Japanese?

[Who Knows]

"Capabilities? as in This person has an unknown Power"

知られぬ力 (ちから） ???? (I really got no idea...)
