NightDarker 

The nemesis and polar opposite of spaceman, and a known gatorade fiend. Writes in barely comprehensible ebonics.

May in fact be spaceman himself, or merely a clone gone bad.

Spaceman
Fighter of the NightDarker man
Champion of the sun
You’re a master of weird posts and snowmen…for everyone

nightmaker 

someone who is soo funny to go out and get drunk with,
and who does really stupid shit that is so eventful and funny.

All this coupled with a great sense of how to get kicked out of night-clubs and sleep in hedges...and still maintains their grasp of the night's hilarity.. this is a true master.

Mostly come under the guise of the alias name, "Jack Clark".
