Zipacna actually used the proceedings to "tag" each of the Tollans ion cannons in preparation for an attack on Tollana. When Skaara was awarded priority, Zipacna ordered his Ha'tak to attack. Teal'c and the Nox Lya hid one of the Ion cannons, and used it to destroy the mothership, though Zipacna escaped through the Stargate. Zipacna was referred to as "Zippy" by Colonel Jack O'Neill.
