Samuel Sullivan is the head of a carnival ring, working with other evolved humans. He refers to his carnival as his family and has recently decided to come out of hiding after killing his older brother. Having lived an early life of service, Samuel feels liberated by the world of abilities and the family he has made. With the goal to create a new home for everyone with abilities, Samuel's actual intentions were to create the fantasy life that his true love Vanessa Wheeler always wanted. Upon being rejected by Vanessa, Samuel made the decision that he will no longer hide or live by the outside world's rules. Samuel is an evolved human with the ability to manipulate geological materials such as dirt and rocks. Samuel is also able to amplify his power when surrounded by other people with abilities. After being defeated by Peter, he has now been arrested.

Samuel has the ability to move earth and manipulate minerals with the power of his mind. He has shown that he has a mental influence over the earth, as well as a form of ink. In addition, Chandra Suresh postulated that the presence of large numbers of evolved humans in a single area produces a phenomenon similar to magnetism, which has the effect of amplifying Samuel's abilities. As a consequence of this, he can also sense when powerful evolved humans are near (Slow Burn).
