Comic-Con 2018 Cosplay Attendees Amp Things Up on Day 1

Attendees at Comic-Con's 2018 Cosplay immediately kicked things into third gear Day 1 with their studio-quality costumes ... trust us, they're incredible.

Comic-Con kicked off Thursday in San Diego and tons of fans flooded the city showing off their super fashion sense. It's pretty awesome ... from some freakishly realistic-looking Teenage Mutant Ninja Turtles and The Flash to an adorable family rocking The Incredibles' costumes. 

Don't call them nerds anymore. They look like they can kick your ass ... and in style.
