“Upgrades” is episode three of season four of Stargate SG-1.
The Tok’ra arrive at the SGC with some technology from the Atoneiks, a race that came and went before the rise of the Goa’uld.
The devices fasten to the arm and give the wearer incredible speed and strength, as well as boosting other abilities. The devices won’t work on the Tok’ra, because of the symbiote, so the Tok’ra who brought them wants to try them out on humans (basically as lab rats), so that she can gather data – and she’s kind of pushy about it.
Jack, Daniel and Sam test the armbands and initially everything looks good, with the team seeing improvements in all areas. On the armbands is an inscriptions saying ‘With great power comes great responsibility’ – rather famous for being said by Spider-Man a lot.
Of course, something that seems this good is bound to have something seriously wrong with it. Especially when the armbands don’t come off.
