We first discuss the stellar and wind parameters of ζ Pup resulting from detailed UV diagnostics. These parameters together with the runaway nature of the star can most easily be explained by dynamical binary-binary or binary-single star interactions in dense stellar clusters. In this case ζ Pup is most likely the merger of at least two massive stars.
