At least in one universe, Phobos was one of the two moons of Mars, alongside Deimos. Its name allegedly meant “Flight”. (COMIC: On Earth)

In the real world, the moon Phobos was named after the deity of the same name whose name actually means “Fear” (as reflected by the modern English “phobia”) rather than “Flight”.
