Hostile Action Displacement System

The Hostile Action Displacement System (or HADS for short) is a defensive system created through Gallifreyan technology. When the object the system is attached to is under threat or attack, the HADS immediately transports the object to another location (and sometimes time), often (but not always) a short distance away out of sight from the original threat. While mainly installed in TARDISes, it can also be built to function in a portable form, allowing the absolute protection of an individual from all forms of harm. The only known drawback of the system is that it needs to be manually set by the user.

HADS-R

(Hostile Action Displacement System (Redirect))

Created by Sakura Xadium Aino, this modification of the HADS system does not move the user, but rather the attack, redirecting it back to the aggressor usually a second or two before it is launched. A large drawbacks of the system include the fact that retaliation is instant (so if you're trying to talk an enemy out of attacking you wit the aim of saving them and they attack you, they get harmed and if time displacmeent is on it looks like you did it to them first). A proposed modification to overcome this are to have the attack simply shunted elsewhere.
