Team X is an organization created for the capture, study, and training of Legendary Pokemon. The organization is named so due to the last words Zero spoke to Professor Helix Blackwood before quitting Helix Studies Inc. ,"I'll make an organization that will be the end of you, Helix!" As a pun, Zero named the Organization Team X, as the letter 'X' is the last letter in Helix's name. 

Team X has a group of 5 Admins, each given a number to represent their ranking in the organization.
