Will (Worlds in Time)

Will was an "assistant" of the Eleventh Doctor.

According to one possibility, this companion may have helped another companion hunt for time shards along other assistants. Other possible assistants in these adventures included Darren, Mal, Meera, Noma, Nneka, Silas, Steven, Talia, Camile, and Gethin.

The possible worlds Will may have visited included Earth, Ember, and Messaline; where he would meet aliens such as Autons, Clockwork Droids, and Zygons. Will may have once been a part of UNIT, as he occasionally would wear a UNIT cap. (NOTVALID: Worlds in Time)

Behind the scenes

 * Unlike the controller-created companion, Will was an automated character designed to work with the player. He, along with Darren, Mal, Meera, Noma, Nneka, Silas, Steven, Talia, Camile, and Gethin, were already designed to be in the game.
 * These assistants were certain to appear in the first playthrough of the early Earth campaign, but later could be replayed by other users playing the MMOG.
