He later recruited the bestial being known as Mangog in what  was yet another test. As Mangog enlisted the aid of Thor, Jones summon Genis, the son of the original Captain Marvel, with whom he was bonded. The trio revealed the truth of Marlo's rebirth, and the severity of the threat they all faced.Walker alongside Thanos. Walker overcame them, and continued to torture Rick Jones, warping time around him and aging him many years as a result.

It was as Thanos well knew, Death was not only a taker of life, but also Marlo and attacked Walker, promising to cause the former Death-God an eternity of torment. Death restored Marlo's life, and promptly returned to her realm.
