So he was bulletproof? So what? His surroundings weren't so he was firing at him and weakening supports at the same time. Who said I was aiming for you? His pauldrons were getting ripped off and he'd webbed the Knight's eyes - just as he'd anticipated and when both armor pieces came off a bunch of flares went off from under the pieces right in the symbiote's face while Saber seeing through the webbing thanks to the bright light chopped a column in half bringing down some ceiling on top of Venom.Thanks for the sunscreen, sucker!
Victor was a very cautious man by nature so he'd done his homework. All he was able to do was stall that... that thing and as much as he didn't wanna admit it this was a losing fight. He had to get out of the building because the enclosed space was giving Brock too much of an advantage so before the monster could get up Saber flew outside trying to get somewhere without people settling for a big empty parking lot.
