Synopsis for "What If... Venom Had Possessed the Punisher"
Frank Castle was at the church that Peter Parker ditched the Venom symbiote at, and as a result, became a more violent, powerful, and lethal version of the Punisher, killing Tombstone and the Kingpin. The symbiote began to use Frank's body while he slept, in an effort to take over his body. Spider-Man, along with the help of Daredevil and Moon Knight, learned about the symbiote's plans and confronted Frank.
From there, he began an internal struggle with the symbiote that he eventually won, by vowing to kill himself and the symbiote if he didn't regain control. The symbiote backed down, and Frank remained in control of it, his discipline intact. At that point, the other heroes let him go, worrying that they'd have bigger worries in the future than a more powerful Punisher, and that they might need his help.
