Red Venom Rider / Hulked-Out Symbiote of Vengeance
Red Hulk, Venom and Ghost Rider fused into one
How strong is this big boy?
Considering that Rulk alone has incredible feats (taking on Thor, Silver Surfer and such).
Ghost Rider is a god-like being (a weapon from heaven).
And Venom having the ability to amplify the user's strength, not to mention his small pre-cog (spider sense).
