Thundercats issue 10 shifts focus to the Mu’Tants, exploring Slithe’s memories of his homeworld Plun’Darr and the devastation caused by the Great War with Thundera. As he prepares for battle, unseen observers lurk in the shadows—neither Thunderan nor Mu’Tant—hinting at unseen conflicts. Acclaimed writer Declan Shalvey and guest artist Joe Mulvey collaborate on this introspective, standalone tale.
