Carlos Prates' nickname "The Nightmare" has origins unrelated to his fighting style. In the 2000s, a popular Brazilian children's show called 'Sítio do Picapau Amarelo' (Yellow Woodpecker's Farm) featured a character named Pesadelo, which translates to "Nightmare." Prates' friends believed he resembled this character and nicknamed him accordingly. The moniker from his personal life eventually carried over perfectly into his fighting career. Despite the origin story, the author of the post notes they personally see no resemblance between Prates and the TV character.
Long before Carlos Prates was stopping opponents inside the UFC octagon, a Brazilian children's television character was quietly responsible for one of MMA's more fitting nicknames.
Prates, the fifth-ranked welterweight contender from Brazil, carries the moniker "The Nightmare" — but its origins have nothing to do with his striking or his finishing ability. According to a recent account of the story, the nickname traces back to a popular Brazilian children's show from the 2000s called Sítio do Picapau Amarelo, which translates to Yellow Woodpecker's Farm. The series featured a character named Pesadelo — Portuguese for "Nightmare" — and Prates' friends decided the young fighter bore a resemblance to him. The name stuck, eventually following him into professional combat sports.
The source who shared the story did note, for the record, that they personally see no resemblance between Prates and the cartoon character.

Whatever its origin, few nicknames have aged as well in MMA. The 32-year-old Vale Top Team product has built a 24-7 record and established himself as a genuine threat in the welterweight division. Standing six-foot-one with a 78-inch reach, Prates brings a switch-stance game that generates 3.77 significant strikes per minute at a 55 percent accuracy rate — numbers that reflect both his volume and his precision.
Why it matters
- Prates sits at number five in the welterweight rankings, meaning any opponent he faces carries significant divisional implications
- His striking output and accuracy mark him as one of the more dangerous stand-up fighters in the 170-pound class
- The nickname origin adds a rare human-interest dimension to a fighter better known for highlight-reel finishes than childhood television nostalgia
