Silver Surfer can definitely take Vranx down for the count. Vranx is actually a formidable opponent, but Silver Surfer has fought opponents like Thor and the Hulk in the past. Vranx doesn’t have great defensive feats and Silver Surfer is pretty quick when he’s on the cosmic board. Silver Surfer has the advantage in the battle and he’s going all the way for his win. Silver Surfer wins.
