Condor is a species of giant birds in Final Fantasy VII. They are physically similar to real world condors, only hundreds of times larger. Only one fully-grown condor is ever seen in the game, nesting its egg atop Fort Condor. It stays stationary, protecting its egg until it hatches. Shinra sees the condor as a threat to its Mako Reactor operations, and so tries to push the bird off. A group of resistance fighters decide to protect the rare condor species and garrison Fort Condor to oppose Shinra.
The series of battles become the Siege of Fort Condor. After the final battle, the condor on top of the fort dies in a flash of light that shows the wings of a Phoenix. The egg hatches and a baby condor is born, along with a Phoenix Summon Materia. The baby condor flies off, showing that the species will continue to survive.
Condors have not returned in any game of the Compilation of Final Fantasy VII.
