When the Tok'ra Anise uses the Atanic armbands on the team (except for Teal'c, to his great displeasure) they receive incredible strength, speed and a very fast metabolism. This seems like a blessing at first, but when Dr. Frasier checks up on them, it seems that their bodies and minds can't handle the virus that is causing it all. When O'Neill accidentally hurts Walter (quite badly) they are confined, but with superhuman speed this seems impossible. At this point the real plan of the Tok'ra is revealed. It seemed that Apophis was building a new ship that is superior to the Ha'tak class vessels and need the improved SG-1 to destroy it. Even though General Hammond forbids them, SG-1 embarks on the dangerous mission, and using their superhuman abilities, almost succeeds. When the job was done and they were going back to the Stargate their armbands comes off and leaves them defenseless. When everything seems lost Teal'c comes to the rescue and helps the team escape. Dr. Frasier found anti-bodies in their blood and figured out that the improvements weren't permanent, she alerted Hammond, and Teal'c was sent on his way.
