Lisle was present during the Battle of Char, specifically at the point when the xel'naga device was activated, killing every zerg in its radius and de-infesting the Queen of Blades. Along with Haynes, Lisle stayed behind to protect the device while Jim Raynor led a team into the primary hive cluster. Raynor's team was successful in recovering Kerrigan, but they had to deal with feral zerg running rampant across Char. Raynor signaled for evac and gave Haynes and Lisle the coordinates for extraction. They successfully got the device onto the Fanfare and escaped the planet.
