One day they decided to board a D/Monix transport truck with the intent of stealing power cells, and Zero Cochrane jacked his mind into the security system. When the others discovered the truck was carrying an android and not power cells, Zero noticed a self destruct activate in cyberspace. He warned his friends but was too late and everyone on board was killed in a violent explosion. Search this site for: 2600 (Earth-TRN767)
