Male. DOB: 11/09/02, born in circus. He arrived at the sanctuary in 2004 from a circus, where he was forced to perform circus shows, under mistreatment. He was soon integrated with Matheus and Carol, his brothers, who had been separated shortly after birth, but the reunion was marked by a lot of partying and games. Lucas enjoys being alone and is individualistic, although he is seen interacting with others occasionally. It is common to observe him demonstrating strength, in a bipedal posture, hitting a plastic bottle on his chest and making a lot of noise in an attempt to scare away anyone who intimidates him. Lucas is a strong and centered chimpanzee.
