Background
He ans Esplin 9466 born from the same grub in an artificial Yeerk pool on board a captured Andalite ship shortly after the Yeerk exodus from their home world. It is usual for one twin to become a success and gain power and influence, while the other - designated "Lesser" - is left with nothing though the rare case shows that the superior one and the lesser still able to work together nevertheless. An instance that unfortunately not last long was between Esplin 9466 with his lesser twin. Whilst the superior Esplin whom eventually became the Visser Three, the Lesser ended up left infesting a lowly computer programmer named Joe Bob Fenestre during their invasion together on Earth along an army of Controllers.

Unsatisfied with his lesser status as the infiltrators of the Yeerk Empire, Esplin 9466 Lesser decided to turn his misfortune around. Using Fenestre's knowledge of human businesses, and his own knowledge of advanced computer systems, he created Web Access America, which quickly became the world's leading Internet Service Provider. The success of the company made Fenestre a billionaire and household name, and gave Esplin a vast information network - not only the names and addresses of WAA's subscribers, but more personal information gleaned from e-mails and chat rooms. Esplin quickly gains influence in human society, making him an asset to the Yeerk invasion.

Unfortunately, this costed him his trust and relationship with his brother, whom has became the Visser Three. His popularity, arrogance, and power hunger nature prompt Visser Three to declared him a traitor, forcing him into hiding. Knowing that his twin's host had the ability to morph into animals of all sorts, he equipped his human host's mansion with weapons, ranging from Rottweliers and guards with submachine guns to insecticides and electrical force fields. His guards had instructions to shoot anything that attempted to come close to the house. Though Visser Three knew this, he hestitates to send his underlings to attack as he knew that Lesser still survive without need of Kandrona Ray radiation that normally required by Yeerk to survive.
