PsN Username Ideas?

     Hey guys, I recently got a Play Station 3 and I'll looking for a pretty decent/good username for my PsN (Play Station Network) account. So, I want to ask some people what some good usernames are.

Here are some words that I would probably like to use in my username:

gravity

fusion

darkness

infinity

Also maybe actual words spelled differently, like:

cystem (system)

sabrye (saber)

phlying (flying)

(Note: Not the only ones, there are others, just off the top of my head right now.)

Or maybe something to do with my name: Kevin Lin

Some example usernames I am leaning towards are:

zerogravity101

klin_98

proKnight98

sabryesaord

Those usernames seem really common and awkward. If you have any suggestions, please post them below. Creativity is best! Thanks!

proKnight98 looks ok.

Infinitedarkfusion    A combination of three of yours.   Maybe just skim through a dictionary.
