Something the MCU is severely lacking is the alien symbiote that has given Spider-Man and other Marvel heroes tumultuous times periodically. It's unlikely that as long as Sony holds the majority of the cinematic rights to Spider-Man, fans will ever see Venom or the black Spider suit in the MCU. Well, then again, thanks to the events of Venom: Let There Be Carnage, there might be a small possibility for the Venom symbiote to wreak havoc throughout the MCU. The mid-credits scene there showed Eddie Brock shift from the Spider-verse he's a part of to the MCU. Meanwhile, a similar scene at the end of Spider-Man: No Way Home showed him return to his proper place in the cinematic multiverse.
