Unlike most other enemies, Psi Reavers do not respawn or appear randomly ; instead they only show up in a few fixed locations near the end of the game.
The Psi Reaver is a bit different from other enemies. Rather than attacking it directly, you should instead search for the Brain that powers it, which usually will be hidden nearby, somewhere in either the same or an adjoining room. The Psi Reaver itself is big, tough and does a decent amount of damage, so it's generally not worth attacking directly. Once the Brain has been destroyed, the Reaver itself can be killed for good.
How dangerous they are depends on how well they have hidden their brain structures. If you find a Psi-Reaver Organ, it can be researched with a small quantity of Radium and Technetium for a 25% damage bonus to them.
