It's a bird, it's a plane ... it's Superman!
Or, at least a man in a superhero T-shirt.
The rowdy World Cup spectator ran onto the pitch during today's U.S.-Belgium match in Salvador, Brazil.
The messages, "#SAVE FAVELAS CHILDREN" and "#CIRO VIVE" were also printed on his blue shirt.
The unnamed man briefly interrupted the match during the 16th minute, but security guards were eventually able to escort him off the field.
