Ari Patel was a marine in Raynor's Raiders. Roughly two months after the Fall of Tarsonis, he found himself as part of a Raiders force on the surface of Char, partnered with Chuck Ayers. Descending into a series of tunnels below the surface of the planet, he took point with Ayers and was almost killed by a hydralisk as a result. Unlike Ayers, who was killed by the creature, Patel only received a large cut across his arm. As such, he was able to proceed further down into the tunnels.
Descending further into the tunnels, Patel had two more encounters with the zerg. The first he emerged unscathed. The second however, a zergling descending from the ceiling leaped at him, biting his face off as both of them fell.
