Venom Hulk VS Dark Carnage
The Hulk bonded with the Venom symbiote takes on Dark Carnage, also known as Cletus Kasady, the original Carnage. It was all going well for Venom-Hulk but Dark Carnage stabbed him in the head with his tendrils and imparted his own view of the world to Venom-Hulk. This weakened him and allowed Dark Carnage to remove the Venom symbiote off the Hulk, and combined it to himself instead.
