Most recently, Marvel Girl absorbed a residual echo of the Phoenix Force left in the sword of a previous host, a Shi'ar named Rook'shir.<ref name="Uncanny X-Men #479">''The Uncanny X-Men'' #479 (Dec. 2006)</ref> It was revealed that this energy source was a less powerful (but easier to wield) form of the Phoenix Force.<ref name="Uncanny X-Men #481"/> The echo was powerful enough to allow Rachel to survive in and fly through the vacuum of space without the need for additional protection, as well as being able to hold her own in combat against the tremendous physical power of [[Gladiator (Kallark)|Gladiator]].<ref name="X-Men: Emperor Vulcan 5">''X-Men: Emperor Vulcan'' #5 (March 2008)</ref> These demonstrations were short lived, however, due to its disappearance, which Rachel attributes to Jean Grey.<ref name="X-Men: Kingbreaker #4"/> She now exhibits her standard power levels, however she has later shown the ability to manipulate Phoenix Fire from the Multiverse.<ref>''War of Kings'' #1–6 (May–Oct. 2009)</ref><ref>''Betsy Braddock: Captain Britain'' #1 (February 2023)</ref>
