Jonothon Grimm, also known as Grimm-Chamber, is a clone of the Thing (Benjamin Grimm) created by the Dark-Beast (Henry McCoy of Marvel Earth-295). He is a clone of the Thing enhanced with the DNA of the X-Man, Chamber (Jonothon Starsmore). Grimm-Chamber was a member of Apocalypse's Black Legion, apparently cobbled together in the genetic soup used to created Infinites and other agents of Celestial Evolution. He was led by Blob in confronting what remained of the X-Men.
