Upgrades

The Tok'ra Anise gives Atanik arm devices to O'Neill, Carter, and Daniel that greatly increase their strength and speed. But the devices rely on a virus that is eventually neutralized by the human immune system, causing the members of SG-1 to lose the strength they gained. However, they don't realize this until they are on a mission on PX9-757, a planet where Apophis builds a new prototype mothership.
