This unit is a black, a (balanced/neutral) unit who strives for human progress (currently of the guardian trope). Not to be confused with greens (innocent), silvers (good), or crimsons (evil). Not to be messed with, as this unit is a jack-of-all-trades who is designed to outlast and rend anyone who: preys on the greens; hinders advancement; and threatens the future.
Update: this unit's psyche has split into 4 personalities, resembling the ones mentioned above. Effects unknown.
Update#2: The split has subsided, and all effects have gone, for now.
Update#3: The personalities have taken up residence in the cerebrum's right hemisphere, and will continue to exist so long as the need for progress is evident.
