The cowl's basic design has remained unchanged; however, it has been frequently updated to advance Batman's crusade. The one aspect of the cowl that does undergo variations is the ears, although the length and pointiness of the ears are supposedly primarily due to the style of the artist drawing Batman, and tends not to be tied to the functionality of the cowl in any way. However, artist, Karl Kerchl has drawn Batman's costume vault showing that he has a wide selection of cowls with ears of different lengths (Adventures of Superman #643).
The Batsuit also has "sonar-vision", where signals emitted by mobile phones are converted into images in a similar way to sonar. In order to view the-said images, white lenses fold down from Batman's cowl to cover his eyes. Fox ran the machine to enable the "sonar-vision", but since it went against Fox's morals to spy on 30 million people, Batman built a self-destruct mechanism to allow Lucius to destroy the machine, likely the glowing lcd lenses were never used again.
His actions were violent, and the Jackal revealed he had been engineered to kill the real Peter, Ben, Kaine and Mary Jane. The Jackal further assisted "Peter" by giving him detailed info on various villains and allies of Spider-Man. As a joke, the Jackal said this "Peter" would commit mass "spidercide" on his behalf. Spidercide stole a container of ribonucleic nanocontagium from the genetic research firm Genetech which lead him to have a confront with the New Warriors. Using these materials, Spidercide and the Jackal killed 2600 people in Springville, Pennsylvania by releasing an airborne version of the Carrion virus. This same incident triggered the powers of Helix.

They were also expected to spend $4.96 billion in 2006, up significantly from just $3.3 billion the previous year. The troubled economy has caused many Americans to cut back on Halloween spending. In 2009, the National Retail Federation anticipated that American households would decrease Halloween spending by as much as 15% to $56.31.
