Strangest Planets?

I'm currently trying to delve into the EU, and one of my favorite aspects of the OT and PT were the diverse settings. So, what are some of the most interesting, unique, or strange planets in the EU? Thanks for any input.

 

Telos IV

It's literally had to been rebuilt.

Lola Sayu

That's definitely a planet you don't see everyday.

Mustafar

The fact that is can even support life-forms when the gravitational pull of it's neighboring planets is ripping it apart is a marvel in my eyes.

 

I would have to say Zonama Sekot...for being a planet with Hyper Drive Capability

 

Felucia comes to my mind. It looks so weird with its plants. Looks kinda like Island Socotra here on Earth.

 

I believe Mortis would be up there along with the aforementioned planets.

Zonama Sekot, Onderon and its moon Dxun and Ryloth (EU version not TCW).

 

Well, a couple days ago I had to go to the planet Blenjeel.... I hate those sand worms..... it is kind of a weird planet, definately not among my favorites.

 

Umbara

It's constantly dark due to the rays of it's sun never making it to the surface.

 

a thread in the star wars movies forums and only two movie planet has been mentioned..

how perverse

Felucia

 

Endor's pretty freaky when you get into EU content about it - a "shipwreck island in space" for many species, and very small (at least in most recent sources) for a habitable planet, at only 4900km diameter.
