Human

The most variant?
The most pervasive?

Humans run the world. Well- literally, they make up most of the corp wageslave population. The worker mule of the modern era, humans aren't special and they aren't new enough to garner much attention in any circle. They're not gifted towards any given thing enough to have a workplace typecast (unless "boring" counts), which is as much a detriment as a favor. Sure, they get passed up for the more exciting things in life, but that's also why most humans live decently long lives. Compared to trolls out there eating bullets for security, anyway.

Some select groups might tell you humans are owed the world by being here "first", and others will tell you they're a dying breed no longer needed. Neither sides' opinions much matter though, as humans are here to stay regardless, right where they've been for years. Just surviving. The cockroaches of the intelligent animal kingdom. (No offense to any cockroach spirits currently present.)
