Biography
Niko Konstantin worked as an astronaut for the Roscosmos State Corporation, Russia's space program. He and Andrei Vyshinsky conducted an expedition to the Moon after they lost the signal of a local probe.

While exploring, both Konstantin and Vyshinsky fell into a crater, but survived. Inside it, they found a hidden facility, which they discovered was called the Shrine by its makers. While exploring and taking pictures, the two accidentally opened a door which contained a cryostasis chamber with living Chitauri individuals. The Chitauri then jumped to the two astronauts and killed them.
