Symbiotes are hard to come by. It's not like you can just sit around, waiting for one to just magically fall off Spider-Man, so you can become his arch nemesis. (Okay, maybe Eddie Brock got lucky on that one, but it's not going to happen that way for most people). Instead, why don't you try this hoodie? It might not grant you any super powers, but you can still hate on Peter Parker while wearing it AND it has Venom's face embroidered on the front. It's probably the closest you'll get to being Spider-Man's main villain.
