Ronan the Accuser later reactivated the Sentry and used it in an attempt to reverse the course of evolution on Earth, but it was once again defeated by Mar-Vell. The Kree agents attempt to retrieve the Sentry but are driven off by spy agency S.H.I.E.L.D.. The Sentry was seen again when activated by the Super-Adaptoid, who used the robot as part of his team Heavy Metal in a bid to destroy the superhero team the Avengers. It returned in the "Blackwulf" series, having been found by Ultron, and joins the Underground Legion but was eventually destroyed in the series finale.
