Dylan Brock Creates A Venom T-Rex
With his codex powers, Dylan Brock connects to the symbiote hive mind and is able to remote control the Venom symbiote even though it was hundreds of miles away in a deserted island with Eddie Brock and the Carnage symbiote. Dylan steps into some sort of a portal and gives the Venom symbiote a power boost, changing its shape into a Tyrannosaurus Rex.
