Prerequisite: Alien

This is a variation on Possess and is the main weapon of the Deathworm Morphant see The Eighth Doctor Sourcebook, P. 29), which uses it to take over the bodies of its prey, in order to attack others while hidden.

However, if the alien encounters a lifeform with a significant amount of willpower, it is possible for the alien itself to be taken over.

The alien initiates a physical attack, Coordination vs Strength, as it attempts to enter its victim’s body. Once the alien is successful, it makes a Resolve roll (opposed by a Resolve roll from the victim). If the alien is successful, the victim is possessed (as per the Alien Trait – see Being Possessed in the core book).

If the victim is successful, however, they transfer their consciousness into the alien's form, gaining the use of the alien's abilities. In this way, the alien can be used in a similar manner to a Chameleon Arch, although without the dampening of the users’ identity. The Master ingested a Deathworm Morphant before his capture on Skaro, transferring his mind into the worm and using it to “possess” his own body. When his body was disintegrated, his consciousness survived with the worm, hiding within his own ashes until he was ready to make his escape.
