Project Deca/General

How Does This Work?
Since it's basically impossible to get permission from everyone who's made a series that features in this thanks to half of them being gone, each series universe visited in Project Deca will be considered completely separate from their original universes. For example, Earth 1010 itself will not be visited, but an alternate counterpart of it, Earth 1010-A ('A' = 'Alternate', obviously), will. The only exception to this will be Earth 83, which I can do whatever I want with since it's, you know, mine.

As for the series visited, you'll notice that most of them are the past Featured Series of the Year. Since there were no Featured Series before 2011, I picked Ben 10 Team Tennyson as 2009's representative (it being the first series on the wiki) and Ben 10: Multi Trixes as 2010's representative (it being an extremely popular show at the time).

Summary
Attai Zehn, a man with no past, is recruited by Professor Paradox to travel between worlds and scan key events to create backups in the mysterious Cosmic Archives. Initially seeing this as a boring task, Attai finds himself opposed by forces from the worlds he visits and worlds beyond.

Trivia

 * Every series that lacked a pre-existing Earth number was assigned one based on their date of creation.
 * The various Omnitrixes displayed in the series logo each represent one of the ten main series given tributes during the series.
 * The primary motif of this series is "record-keeping", referencing the encyclopedia-based structure of the wiki format.
