Alexander Hernandez

Alexander Hernandez announced himself in the loudest way possible - a 42-second knockout of respected veteran Beneil Dariush in his UFC debut, followed immediately by big talk about running the lightweight division. For a while the hype outran the results as he ran into the division's best, and his confidence made him a polarizing figure.

But he's rebuilt himself into a gritty, well-rounded action fighter, stringing together wins over the likes of Jim Miller and Chase Hooper. The explosive, fast-starting style is still there, just paired with more maturity. Fans either love the swagger or want to see him humbled - either way, his fights bring action and his personality keeps people talking.
