Update 6/7/2018: The full Asgardians of the Galaxy team roster has been revealed: Angela, the Destroyer, Valkyrie, Throg, Skurge the Executioner and Kevin Masterson, better known as Thunderstrike. The creative team is writer Cullen Bunn and artist Matteo Lolli.
Angela is a former member of the Guardians of the Galaxy, so perhaps when the Guardians disappear, she steps in to fill the void with her own band of unlikely heroes. Marvel’s press release describes the book as thus:
“Spinning out of the events of INFINITY WARS comes an epic spaceopera from the superstar team of Cullen Bunn and Matteo Lolli! ANGELA, the not-so-beloved half-sister of Thor. The hotheaded VALKYRIE – and the human who shares her form, Annabelle Riggs. SKURGE the EXECUTIONER, freshly returned from Hel. THROG, the mightiest frog of thunder. Kevin Masterson, the boy who took his father’s mace to become the hero THUNDERSTRIKE. And the DESTROYER, the Asgardian armor built to take down Celestials – its wielder unknown.”
