The violent start to Carlos Prates' Octagon career continued at the expense of veteran contender Neil Magny at UFC Vegas 100.

Prates had already staked a strong claim for this year's Newcomer of the Year accolade, having followed a contract-winning performance on Dana White's Contender Series 14 months ago with three straight UFC knockouts in 2024.

The Brazilian immediately had his grappling defense tested by Magny, who looked to avoid his opponent's renowned power at any and all cost.

But the 37-year-old quickly found himself hurt and backpedaling after being struck by the prolific knockout artist. And with short time remaining in round one, "The Nightmare" shut Magny's lights out and faceplanted him with a glancing left hand.

Unsurprisingly, the MMA community was abuzz in the aftermath of the Brazilian's latest display of violence. Both fellow fighters and fans took to social media to express shock and awe.

The common theme? "Legit."

"The Haitian Sensation," meanwhile, has now lost consecutive bouts for the first time since 2013. While his year opened in style when he stalled the surge of Canada's Mike Malott, he's now dropped back-to-back outings against two highly regarded names in Michael Morales and Prates.
