The first ever Silicon Valley Comic Con drew huge crowds to downtown San Jose this last weekend and fans were graced with more than just tech giants and Back to the Future attractions. The cosplayers were out in force and as it would be expected there were a lot of Marty McFlys, but the variety was impressive and on par with the larger cons in the state. The con had a small cosplayer alley but attendees could also find well-known cosplayers such The Fatal Siren in her popular Black Cat and Macy Rose, as they walked the floor and enjoyed the attractions. The attendance to the Con by both cosplayers and general fans was a great sign that this first year of Silicon Valley Comic Con will not be the last.
