10HE'S BEEN AN AVENGER (TWICE!)
If Venom is SUCH a villain, how has he been a member of the Avengers multiple times? Okay, one of those times, he was actually a member of Norman Osborn’s Dark Avengers, but that was when Mac Gargan was the symbiote’s host -- so we are just going to gloss over that one. But when Flash Thompson was the Venom symbiote’s host, Captain America agreed to let Venom join the Secret Avengers, a team that included Beast, Hawkeye, Black Widow, and Valkyrie, amongst others.
Flash, without a doubt, took Venom in its most heroic direction to date. Even though the team was very hesitant to trust him, given Venom’s reputation, he acclimated to the pressure of being an Avengers very quickly. Plus, he got Captain America’s stamp of approval, and that’s good enough for us.
