The "General Spider" was much larger than the other Spiders (rivalled only by the Queen) and was also the most intelligent and arguably the most malicious of the swarm as he was actively seeking to murder those that got in his way (though it was likely for what he saw was the survival of his offspring). In the climax of the movie the "General Spider" engages in a fight with the movie's hero after he has the swarm attack the hero's home - which was the site of one of his nests, guarded by the Queen - who the hero killed via electrocution.
