Betazoids

The Betazoids or Betazeds were a telepathic humanoid civilization originating from the Federation planet Betazed in Star Trek.

Externally, Betazoids were physically indistinguishable from Humans in every aspect but one: the irises of their eyes were completely black. They could breed with Humans, along with other humanoid races like Klingons. It is therefore likely that they originated from the Progenitors.

Betazoids were natural telepaths and common psionic abilities of Betazoids extended from sensing thoughts and/or emotions, over projecting thoughts and/or emotions, to manipulating the minds of others.
