Just don't call it a symbiote...
During a recently concluded story arc set in space, writer Saladin Ahmed's Ms. Marvel returned to Earth with a brand new nanotech costume of Kree origin designed by series artist Minkyu Jun. According to Marvel Comics, the costume "holds many secrets and seemingly has a life of its own as a mysterious entity known as Stormranger."
"In the months ahead, this strange being will not only play a major role in Ms. Marvel’s adventures, but in the Marvel Universe as a whole..." reads the publisher's announcement.
Stormranger will be featured on the upcoming second printings of Magnificent Ms. Marvel #7, 8 and #9 with connecting variant covers by artist Luciano Vecchio, which you can check out below.
