After graduating school as one of the best, Jack decided to help younger generations by becoming a teacher in his former school. Being talented in computers, he spend his free days on the computer. One day, the shy Jack gave in to the temptation and hacked a neighbour's computer. Being thrilled by the idea earning profit while being unseen during his illegal work, Jack now used every chance to hack into other people's computer. This finally attracted the attention of the criminal genius Mast3rm1nd Z3r0. Being a top hacker himself, he suggested that he and Jack could work together to earn money. Jack, after hearing about the chances of earning more money than his job would allow him to, accepted. Eventually, he met his old friend Curt Van Clicker, who was now decrypting messages for the military, and convinced him to join them. Thus, the hacker group known as Cerberus was born. Together, the three hackers commited a great hacking attack, by having all members hacking at the same time, which eventually became their modus operandi. Beside his secret work as a hacker, Jack remains a shy man in social life, encouraged only by his two fellow hackers, while struggling with the choice between his dream of teaching the next generation or becoming one of the greatest hackers ever.
