William's Tower Activation

After William fell under XANA's control, Xana has been using William to do his dirty work on Lyoko and therefore gave William the power to control his monsters and assist in the activation of towers. It is unlikely that William is able to activate towers alone, it is however logical that William has the ability to weaken the resistance of towers which allows XANA to activate them quickly as Jeremie had raised defences on the tower to uphold his clone. William has only used this once in Double Take.

It is shown that William has the ability to activate towers by entering the XANA code into the tower interface, he did this on the Replika to break the team's connection to the real world.
