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

The Nightwalker

When getting intimate with a partner, one waits until both are heated up physically and then brings in an outside cold hand to place aggressively on the other's genitalia.

I was so ready to go and then she pulled the Nightwalker and I fucking lost at the Battle of Winterfell.
