I'm going with Venom on this one. Definitely stronger, most definitely faster than the pred. Tryin to hit Venom would be the predator's downfall since his speed is comparable to Spider-Man's (ex: when carnage tosses that baby out of a window and they both go after him, with Venom successfully catching the baby)
I havent read the Predator comics in a while but the idea of Elders lifting tanks sounds like the biggest load of crap ever written in a comic. Preds are supposed to be badasses because they're cunning hunters and powerful (due to their size advantage compared to humans), but not so powerful as to be able to lift a tank.
Just out of curiousity, when did elder preds become so damn strong? I have a comic book where an elder gets maced by one frickin drone alien.
Also the symbiote can alter the surface temperature of the hosts body. It did this to fake Eddie's death by covering and mimicking his skin so it was cold to the touch so he could escape from the morgue in the Vault.
