Paragon is the codename used by two unrelated fictional characters from Marvel Comics. The first was genetically engineered by the Enclave. The second is a superhero and a member of Nebraska's Initiative team.
After investigating an unsolved crime with teammate Gadget, they ran across a formerly missing supervillain, Graviton. In a sudden flurry of violence, Roth was badly injured, requiring hospitalization and Gadget was killed. Graviton was taken into S.H.I.E.L.D. custody. After an investigation by Iron Man turned up evidence implicating Roth, Iron Man confronted Paragon and was subsequently attacked by Captain Ultra. In a following issue, it is revealed that Paragon is under the influence of the Mandarin, who manipulates him into believing that Graviton is responsible for the death of his mother. Roth then attempts to assassinate Graviton, who instead kills Roth before then taking his own life.
