Biography[]
When the Battle of New York ended, Cox and company apprehended Loki. As they brought him downstairs with Thor and Iron Man, they were approached by Alexander Pierce. Although Pierce wanted the Tesseract, the argument was halted by Stark's cardiac arrythmia. As everyone helped Stark, Cox guarded Loki. However, he failed as Loki obtained the Tesseract and jumped away.[1]
