CF Massacre stands for "Corumbá Family Massacre." Caio Henrique's murder of Alexandre Corumba and his entire family was a brutal act of vengeance, fueled by past trauma. One of Corumba's sons had relentlessly bullied Caio during his youth, driving him to seek revenge years later. Corumba, a skilled capoeira and kickboxing master, encountered Caio, who flaunted a background in MMA and Muay Thai. However, in this fateful confrontation, Caio emerged victorious. Corumba's family, which numbered more than 10, fell victim to Caio and ISG's cold-blooded killings; including the son who was a former bully. Though he claimed repentance, ISG is known for perpetuating the "no mercy motto" when it comes to murderers and criminals overall.
