Martinete
Known elsewhere as the piledriver; the Tombstone version of the move is most commonly used. Universo 2000's sit down version is known as the Martillo Negro (aka Black Hammer). These moves are illegal in standard lucha libre matches.
Martinetes were originally banned for safety reasons, after a wrestler was paralyzed receiving one. The intention of the rule seemed to ban all piledriver variations, ending a match in a disqualification immediately after use. Over time, this banishment has been reduced to just banning the two moves pictured on this page. Other piledriver variations or moves with similar potential for neck trauma are allowed (e.g. the Canadian Destroyer, Volador Spiral, Rush Special, Package Piledriver etc.). The rule isn't forgotten or ignored, as questionable moves usually lead to debates between the announcers over the move's legal status, but the ban has evolved into less of a safety concern and more of a unusual match finish. From a psychological standpoint, its possible that variants are permitted as they showcase advanced "technique", whereas the basic piledriver is very rough, ugly, and serves only to hurt in the most direct way possible.
Martinetes are essentially more impactful versions of fouls, with the victim usually being taken to the back on a stretcher and possibly missing a few weeks of action. There's no more powerful move in lucha libre than a martinete.
Unlike fouls, if a wrestler manages to execute a martinete without the referee(s) noticing, the attending representative of the local Box y Lucha commission may overturn the referee decision and rule a DQ due to the level of offense.
CMLL eventually gave up the pretence of the move being banned whilst other more devastating-looking versions were not in the 2020s, with the first instance seemingly being when Reyna Isis hit a tombstone on La Jarochita in their mask vs mask match at CMLL 89th Anniversario in full view of the referee and was not disqualified. The commentators explained this as the move "not being prohibited" (with a vague caveat that it depends on the "harshness of the punishment" and that "the referee doesn't consider the roughness [as enough to DQ])". Other notable examples include Atlantis Jr. hitting one on Kyle Fletcher in his ROH World Television Championship win, MJF tombstoning Mistico at the CMLL 92nd Anniversario, and Soberano Jr. adopting the Black Hammer as his regular finisher.
