Ol' Blue was used to track a missing egg which was stolen by Ahiro, a procurer from Synsound. During the mission, Blue had crushed an addict to death while tracking the missing egg, the security team realized why, the addict had Xeno-Zip which was taken from a rival hive causing Blue to become highly violent. Blue successfully leads the team to the lab where the stolen egg was taken but they realize it had already hatched. They place Blue in Mozart's cage while they deal with the threat. The team eventually kills Ahiro and Mozart, ending the threat.
- Ol'Blue is one of the few cases where a Xenomorph is used successfully as a tool of mankind without it turning on it's handlers as Xenomorphs have frequently been known and expected to do.
