Eloi vs. Morlock — What's the Difference?

The Eloi are one of the two fictional post-human races, along with the Morlocks, in H. G. Wells' 1895 novel The Time Machine.

Morlocks are a fictional species created by H. G. Wells for his 1895 novel, The Time Machine, and are the main antagonists. Since their creation by H. G. Wells, the Morlocks have appeared in many other works such as sequels, films, television shows, and works by other authors, many of which have deviated from the original description.
