The fourth celebrity to enter the house during their edition's run after Albie Casiño (who entered five days before his entry), Benedix is the co-winner of the Online Bahay ni Kuya campaign held on Kumu along with fellow streamer Jordan Andrews. Benedix officially entered the House on Day 17 while acting as a punishment officer due to Big Brother kicking out the celebrity housemates in his house and they must stay in a jail-like room in the Activity Area until his given time. He also kept his housemate status a secret.
During his time as a punishment officer, he was commonly teased by the housemates, especially Madam Inutz and Brenda Mage, who would accidentally had a crush on him after seeing him at the Activity Area. But, he would also give an abswelto (acquittance) envelope to the four celebrity housemates (2 male and 2 female celebrity housemates) that had their actions improved during their stay.
At the time that they were finally released from the jail-like room, Big Brother then announced that Benedix will become the next celebrity housemate, to the surprise and hype of the current celebrity housemates.
Benedix got his first taste of immunity on Day 34 after his team, the Bigateam, consisting of himself, Brenda Mage, Eian Rances, Karen Bordador, and TJ Valderrama won the first Pinoy Big Brother Games 2021 after accumulating a total score of 55 points after three games.
Benedix would then be nominated for the first time during the third nominations, but was saved, placing second place. He was then nominated for the second time in the sixth nominations after losing to the the Blue Team on the Tower Task group challenge where Benedix's group (the Yellow Team) lost and would then be the nominees for eviction. He would then fell victim as the first evictee of the sixth eviction night after having the second least percentage of save-to-evict votes along with Shanaia Gomez.
