- "Release me, I just want to live! Get off me!"
- —Roberto pleading for his life (Translated from Portuguese).[src]
Nothing is known about Roberto's life before or as the outbreak began. He may have originated from a Portuguese-speaking country such as Portugal or Brazil as he doesn't speak English very well.
During Shel's story, Roberto attempts to break into Gil's Pitstop to steal supplies, but is caught by the "watchdog" zombies that were put out to guard the surrounding area. During this time, some of the camp members, Boyd, Clive, and Joyce gather together to examine Roberto.
After Roman blindfolds Roberto's eyes and binds up his wrists, Shel, Becca, and Stephanie approach to see what is going on. Roberto is unable to communicate in English, and murmurs a few words in Portuguese. He is covered in cuts and bruises, though Roman states they were not his doing. Clive and Joyce distrust the stranger and do not believe he should be allowed to still live while Boyd and Stephanie want to have mercy on the man and let him go. Roman allows Shel to make the final decision in the swing vote in whether Roberto lives or dies.
If Shel decides to let Roberto go, (Determinant) Roman will send the man on his way unharmed. Later, Roberto returns to Gil's Pitstop with a number of bandits to raid the group's camp, though Boyd will be one of the casualties as a result of the ambush attack. His fate afterwards is unknown. If Shel views him as a threat, (Determinant) Roberto is shot in the head by Roman causing Roberto's group to attack causing the death of Clive
If Shel sides with Joyce and Clive in the decision to kill Roberto or Roman votes himself and chooses that Roberto should die, he will be executed by Roman. As a result their camp will still be raided by bandits killing Clive.
This list shows the victims Roberto has killed:
- Roberto is the first Portuguese character to appear in The Walking Dead.
- Jason Pimentel, Roberto's voice actor, is a Localization Tester at Telltale Games.
- If the player stays silent when given the option to kill or free Roberto, Roman will decide for them based on their earlier dialogue choices as Shel.
