The Skidbladnir is saved

Yumi saves Ulrich from defeat at William's hand, knocking William's sword out of his hand. This doesn't stop William from stealing Ulrich's own saber later on and using it to devirtualize him.<br><br>Aelita defeats William with a particularly charged Energy Field when he's about to destroy the ship, also becoming the first person to defeat him.<br><br>Finally, Jeremie is able to finish the ship's programming with 10 seconds to spare.<br><br>All the while William's theme plays as both Lyoko-warriors and XANA pull out the big guns.
