Doppelganger's death

During the Infinity War, Magus created doppelgängers of heroes and sent them to Earth to attack the heroes. When Doppelganger encountered Spider-Man, Spider-Man was already engaged in battle with the Hobgoblin. Hobgoblin defeated the doppelganger by impaling it on a fence. Later Demogoblin found Doppelganger and infused it with supernatural energy. This energy allowed Doppelganger to remain on earth after Magus was defeated. Doppelganger was directed to a grudge against the Hobgoblin. When Doppelganger and Demogoblin teamed up to defeat the Hobgoblin, Spider-Man protected the Hobgoblin. As the battle continued, it led to them joining another battle where Dan Ketch and Johnny Blaze battled a group of Deathspawn and Venom. Doppelganger and Demogoblin are pulled underground by the Deathspawn and two deathspawn take residence within Doppelganger. After that, Doppelganger lurked around New York until the Maximum Carnage storyline. Doppelganger ran into Carnage who mistook Doppelganger as Spider-Man. Shriek liked Doppelganger and took it as a son. During their spree, Demogoblin and Carrion join the group. Carnage's 'Family' battle Spider-Man, Black Cat, Cloak, Venom, and others. When Shriek started showing rebellious behavoir, Carnage attacked her. Doppelganger defended Shriek until it got gutted and kicked into the street by Carnage.
