mark gives Venom control over demons; after a demon tries to possess him it becomes trapped in Thompson's body, unable to leave or control him. Venom must contend with Hellstrom, who is possessing monsters with demons (creating an army to help him become Mephisto's chosen heir). Venom #23 (November 2012) introduced a new supporting character in journalist Kate Kiernan. The 2012 story "Minimum Carnage" saw the series cross with Scarlet Spider to feature Venom and Scarlet Spider against an escaped Carnage in the Microverse. The story concludes with Carnage defeated and lobotomized by Scarlet Spider, leaving the Carnage symbiote in control of his body and Venom able to sense Carnage's presence. The events of "Monsters of Evil", "Minimum Carnage" and his fear of the symbiote controlling him prompt Thompson to move to Philadelphia in Venom #27.1. Thompson is possessed by the demon inside him while he sleeps, and terrorizes people as Venom. In Philadelphia, Thompson gains employment as a high school gym coach, while as Venom he comes into conflict with the U-Foes, who kidnap and experiment on victims with alien technology. When the U-Foes knock Venom, the demon takes control of his body and uses the alien technology to teleport the villains to their apparent death in space. Kiernan and Thompson's lover Valkyrie later return home, leaving Venom alone. Brock returns as Toxin in Venom #30, to pursue Thompson while he himself is hunting the result of one of the U-Foes experiments: an alien-lifeform infested human turned into a cannibal. Thompson and Brock's fight liberates the aliens who begin infecting and transforming other humans to target their new enemies: Venom and Toxin. Together, Thompson and Brock defeat the aliens, and afterwards Brock calls a truce with Thompson, promising that the Venom symbiote will inevitably take over Thompson, and that he will return to kill him when that happens. Venom #39 sees the return of Jack, and the introduction of the new symbiote character Mania—Thompson's teenage student Andi who bonds with a spawn of the Venom symbiote when Thompson uses it to protect her from Jack. Jack kills Mania's father, and is revealed to be merely a man who was brainwashed by some of Jack's technology into believing he is the real Jack. According to Bunn, when he envisioned a new symbiote character Andi was not intended to be the host, but as the series progressed his plans changed. It
