I’ll volunteer the name reserved for the dog I’m getting in a month:
Basil von Peepers
Sounds rather regal for a hamster.
Gereplug
Oooh–Odinoneeye - I get the Stephen King reference.
How about Horatio H. Hamster? Or “Triple H” for short.
I knew a guy with a dwarf hamster named Gimli
Burpy.
Pamster (if it’s a girl) 
I suggested “New Hamster” when my daughter got her new pet but she went with “Peanut”.
Is it a Golden ( Syrian ) Hamster? If so, the stem population derives from several pairs imported from Aleppo. Therefor a good Aleepo name is called for. The only independent dynasty that was more or less centered exclusively on Aleppo were the 11th century Bedouin-origined Mirdasids. The ruler to choose here would be one Nasr I, Abu Kamil Shibl al-Dawla who in 1030 managed to panic and defeat a vastly superior Byzantine army under Emperor Romanus III ( and this when the Byzantine state was at it’s height, though it was about to begin its slide downward under incompetents like Romanus III ).
So there you go - “Nasr” :D.
- Tamerlane
Frankly I prefer Tamerlane as a name for a hampster to put the fear of God into you… 
Schobel von der Grau. Not only a title, but a foreign-sounding one as well! (Nobody has to know you’re just calling him “Gray Schobel”.)
No, wait - Schobel von Graufell - “Schobel Graypelt”. Accurately descriptive foreign-sounding title. Perfect hamster name!
Now I love “Reepicheep.” Even though he was a mouse.

We got a hamster as a class pet and I wanted to name him (her? it?) Hamlet, but my students didn’t get it and named him Peanut Butter. He was pretty cool for a hamster–escaped one spring and was found 3 months later in the cafeteria…alive, fat and happy. He died one day while I was out sick and the principal wanted to throw him away, but my kids insisted otherwise and I came back the next day to find him in a shoe box in the nurse’s freezer. We buried him out back of the classroom. Had a burial ceremony, read “The Tenth Good Thing About Barney,” an awesome kid’s book by Judith Viorst about the death of a pet (sniff, sniff), and marked his grave with a popsicle stick cross. Guess he was a Christian hamster.
My vote: Hamlet
