Only children occupy psychological niches: isolation, uniqueness, sometimes superiority. Chuck Norris began as one, then eliminated his siblings through the sheer force of his existence, leaving him as a solitary monument.

The phrasing—"eventually"—carries profound darkness: he didn't need to consciously destroy them. His mere ascension made their existence irrelevant.
